a pointy pony can work at the rate of 0.5 hp if the pony pulls a load with a steady force of 170 n how fast can she go

Answers

Answer 1

A pointy pony can work at the rate of 0.5 hp if the pony pulls a load with a steady force of 170 N .The pony can travel at approximately 2.19 meters per second (m/s) while exerting a steady force of 170 N.

To determine how fast the pony can go while exerting a steady force of 170 N, we need to convert the given horsepower (hp) value to watts (W) since the SI unit for power is watts.

1 horsepower (hp) is equal to approximately 745.7 watts.

Given that the pony can work at a rate of 0.5 hp, we can convert it to watts:

Power (P) = 0.5 hp ×745.7 W/hp

P ≈ 372.85 W

Next, we can use the formula for power to calculate the velocity (v) at which the pony can go while exerting a steady force:

Power (P) = Force (F) × Velocity (v)

Rearranging the formula, we have:

Velocity (v) = Power (P) / Force (F)

Substituting the values:

v = 372.85 W / 170 N

v ≈ 2.19 m/s

Therefore, the pony can travel at approximately 2.19 meters per second (m/s) while exerting a steady force of 170 N.

In which dimensions do we find the components of acceleration (tangent and normal vector)?Let's say,

Answers

The acceleration of an object can be split into two components: the tangential and normal components. The tangential component points along the direction of motion and is responsible for changing the speed of the object. The normal component is perpendicular to the direction of motion and is responsible for changing the direction of motion.

In your skiing example, the direction of your acceleration will change as you move uphill, downhill, up a ramp, and make a turn. Therefore, the tangential and normal components of your acceleration will also change in direction and magnitude.

As you ski uphill, your acceleration will be pointing in the opposite direction of your motion, resulting in a negative tangential acceleration. Since your motion is mostly vertical, your normal acceleration will be pointing upwards.

As you ski downhill, your acceleration will be in the same direction as your motion, resulting in a positive tangential acceleration. Your normal acceleration will still be pointing upwards.

When you go up a ramp, your acceleration will be a combination of tangential and normal components. The tangential component will be pointing upwards to match your velocity, and the normal component will be pointing perpendicular to the ramp.

When you land, your acceleration will be mostly normal, as you decelerate your downward motion and start to move horizontally.

Finally, when you make a turn, your tangential acceleration will be pointing in the direction of the turn, while your normal acceleration will be perpendicular to the turn.

Overall, the direction and magnitude of the tangential and normal components of your acceleration will depend on the direction and magnitude of your velocity and the curvature of your path.

Answers

Two small plastic spheres are given positive electric charges. When they are 15.0 cm apart, the repulsive force between them has a magnitude of 0.72.

How many electrons had to be removed from one sphere and added to the other to cause an attractive force between the spheres?The answer is given below:Concept:Charge on an electron, e = 1.6 × 10^-19 C. Coulomb’s law gives the magnitude of the electrostatic force, F, between two charges, q1 and q2, separated by a distance, d. It is given by:F = kq1q2/d2where, k = Coulomb’s constant = 9 × 10^9 Nm^2/C^2.Force, F = 0.72 N, distance, d = 15 cm = 0.15 m. We know that the repulsive force is due to the fact that both charges are positive, meaning both are deficient in electrons. To create an attractive force, electrons from one sphere must be transferred to the other sphere. Let x be the number of electrons transferred, then each sphere acquires an additional charge of -xe.Since the force is attractive, the charges on the spheres are of opposite polarity. Let the charges on the spheres after transferring electrons be q1 and q2 with q1 < 0 and q2 > 0. Then we have:k|q1q2|/d2 = k|(-xe) - (xe)|/d2 = kx2e2/d2 = 0.72 NThe number of electrons transferred to create an attractive force between the spheres is given by:|x| = 1.2 × 10^13

First, we determine the total charge on each sphere.The magnitude of the repulsive force between the spheres is given by:Coulomb's law:$$F=\frac{k q_1 q_2}{d^2}$$$$0.72=\frac{(9\times 10^9)q_1q_2}{(0.15)^2}$$Simplifying the equation:$$q_1q_2=\frac{(0.72)(0.15)^2}{9\times 10^9}$$$$q_1q_2=1.08\times 10^{-11}$$Let the charges on the spheres be $q_1$ and $q_2$ such that $q_1<0$ and $q_2>0$. The difference in charges between the two spheres is given by:$$q_2-q_1=\frac{(0.72)(0.15)^2}{9\times 10^9}$$$$q_2-q_1=1.08\times 10^{-11}$$Add the same number, $x$, of electrons to one sphere and remove $x$ electrons from the other sphere, so the charges on the two spheres become $q_1-xe$ and $q_2+xe$, where $e=1.6\times 10^{-19}$ C is the charge of an electron. The difference in charges between the two spheres after the electrons have been transferred is:$$q_2+xe-(q_1-xe)=q_2-q_1+2xe=1.08\times 10^{-11}+2xe$$The electrostatic force between the spheres after the transfer of electrons is:$$F=\frac{k(q_1-xe)(q_2+xe)}{d^2}$$$$=\frac{(9\times 10^9)(q_1q_2+(q_2-q_1)xe+x^2e^2)}{(0.15)^2}$$Substituting the value of $q_1q_2$ and the difference in charges, $q_2-q_1$:$$0.72=\frac{(9\times 10^9)(1.08\times 10^{-11}+2xe+x^2e^2)}{(0.15)^2}$$Simplifying the equation:$$x^2=3.6\times 10^{22}-2.0\times 10^{13}x$$$$x^2+2.0\times 10^{13}x-3.6\times 10^{22}=0$$Using the quadratic formula:$$x=\frac{-2.0\times 10^{13}\pm \sqrt{(2.0\times 10^{13})^2+4(3.6\times 10^{22})}}{2}$$$$x=-1.0\times 10^{13}\ \text{or}\ x=3.6\times 10^{9}$$The number of electrons transferred to create an attractive force between the spheres is:$|x|=3.6\times 10^{9}$

Answers

Answer:

An 8 kg sled mass moves in a straight line on a surface without horizontal friction at a certain point its speed is 4 m / s 2.50 m later its speed is 6 m / s using the work and energy theorem, determine the force acting on the sled assuming it is constant and acts in the direction of the sled movement

The force acting on the 8 kg sled has a value of 32 N.

Explanation:

We have initially look for the work that is applied to the sled, and this will be nothing more than the difference in kinetic energy from the end point to the initial, then:

ΔEc = Ec₂ - Ec₁

ΔEc = 0.5 * m * [V₂² - V₁²]

ΔEc = 0.5* 8 kg * [(6m / s) ² - (4m / s) ²]

ΔEc = 80 J

So, the work is 80 J, now we know that work is a relation distance and force , such that:

W = F * d

F = W / d

F = (80 J) / (2.50 m)

F = 32 N

Therefore, the force acting on the sled is 32 N.

find the coefficient of kinetic friction μkμkmu_k . express your answer in terms of some or all of the variables d1d1d_1 , d2d2d_2 , and θθtheta .

Answers

The coefficient of kinetic friction μk relates the frictional force between two surfaces to the normal force pressing the surfaces together, and it depends on the nature of the surfaces in contact.

If an object of mass m is moving on a horizontal surface with a constant velocity v, the frictional force f_k acting on the object is given by:

f_k = μ_k * N

where N is the normal force, which is equal in magnitude to the weight of the object when it is on a horizontal surface. Thus, we have:

N = m * g

where g is the acceleration due to gravity.

In the situation where an object of mass m is sliding down an inclined plane with an angle of inclination θ, the gravitational force acting on the object can be resolved into two components:

A component mg * sin(θ) parallel to the plane, which causes the object to slide down.

A component mg * cos(θ) perpendicular to the plane, which is balanced by the normal force N.

The kinetic frictional force f_k acting on the object is then given by:

f_k = μ_k * N

Substituting for N, we get:

f_k = μ_k * m * g * cos(θ)

Since the object is sliding down the inclined plane with a constant velocity, the kinetic energy is constant, and the work done by the kinetic friction force must equal the loss in potential energy of the object.

Thus, we have:

f_k * d_1 = m * g * (h_1 - h_2)

where d_1 is the distance traveled along the incline, h_1 is the initial height of the object, and h_2 is the final height of the object. Solving for μ_k, we get:

\(μ_k = (m * g * (h_1 - h_2)) / (f_k * d_1)μ_k = (m * g * (h_1 - h_2)) / (μ_k * m * g * cos(θ) * d_1)μ_k = (h_1 - h_2) / (cos(θ) * d_1)\)

Therefore, the coefficient of kinetic friction μ_k can be expressed in terms of the variables d_1, h_1, h_2, and θ as:

μ_k = (h_1 - h_2) / (cos(θ) * d_1)

Answers

The image of the 12-inch object produced by a plane mirror placed 30 inches in front of it is 12 inches high. This is because the image is the same size as the object and is located at the same distance behind the mirror as the object is in front of it.

The angle of incidence of the ray of light striking the mirror is not relevant to the size or position of the image produced by the mirror.In a plane mirror, the angle of incidence is equal to the angle of reflection. This means that the angle between the incident ray and the mirror is equal to the angle between the reflected ray and the mirror.

If the incident ray strikes the mirror at a 45-degree angle, then the reflected ray will also be at a 45-degree angle with respect to the mirror. This will not affect the size or position of the image produced by the mirror. Therefore, the image of the 12-inch object produced by the plane mirror is also 12 inches high and is located 30 inches behind the mirror, as if it were a real object.

Assuming the force required to lift the rope is equal to its weight, find the force function, F(x), that acts on the rope when the bucket is at a height of x ft.
F(x)=

Answers

The total work done in lifting the bucket and rope is 187.2 foot-pounds (ft-lb).

To find the work done in lifting the bucket and rope, we need to consider two parts:

Part 1: Work done lifting the bucket (without the rope) 24 ft:

The work done in lifting the bucket can be calculated by multiplying the weight of the bucket by the distance it is lifted.

Given:

Weight of the bucket = 7 lb

Distance lifted = 24 ft

Work done lifting the bucket = Weight of the bucket x Distance lifted

Work done lifting the bucket = 7 lb x 24 ft

Please note that the units need to be consistent for the calculation. In this case, we have pounds (lb) and feet (ft).

Part 2: Work done lifting the rope:

Assuming the force required to lift the rope is equal to its weight, we can calculate the work done lifting the rope by multiplying the weight of the rope by the distance it is lifted.

Given:

Weight of the rope = 0.8 lb

Distance lifted = 24 ft

Work done lifting the rope = Weight of the rope x Distance lifted

Work done lifting the rope = 0.8 lb x 24 ft

Now, we can calculate the total work done in lifting the bucket and rope by summing up the work done in both parts:

Total work done = Work done lifting the bucket + Work done lifting the rope

Please note that the units of work are in foot-pounds (ft-lb).

Now, we can calculate the values:

Work done lifting the bucket = 7 lb x 24 ft = 168 ft-lb

Work done lifting the rope = 0.8 lb x 24 ft = 19.2 ft-lb

Total work done = 168 ft-lb + 19.2 ft-lb = 187.2 ft-lb

Therefore, the total work done in lifting the bucket and rope is 187.2 foot-pounds (ft-lb).

Answers

Answer:

c. may be accompanied by the sound of explosively expanding hot air, called thunder.

Explanation:

Lightning is a discharge which is due to the reaction between oppositely charged charges in the clouds, or between clouds base and the Earth surface.

The motion of the cloud causes charging of clouds by friction, thus the reaction between opposite charges (jumping of charges from one cloud to another) in the cloud can lead to lightning. Also, oftentimes the bottom of a cloud is negatively charged so that this is attracted to the positive charge on the earth surface. Thus leading to a discharge called lightning.

Thus in the given question, the appropriate option is C. This implies that, lightning may be accompanied by the sound of explosively expanding hot air, called thunder.

Answers

The bullet's undetermined mass is m1 = 1.458 x 103. Mass, in physics, quantitative measure of inertia, a fundamental property of all matter.

Newton's equations of motion state that when a body of mass m is subject to a net external force, the body's momentum changes and is represented by:

f = p/dt

Where:

P is the body's linear momentum.

As a result, the total momentum of the body remains constant in the absence of any external forces, i.e.

Calculation:

m2 = m3 = 4.5 x 10-3 kg

v2 = v3 =  575 m/s

The equal masses must move at angles of to each other in order for momentum to be zero in the y-direction.

θ1=180°, θ2=60°, θ3=-60°

Consequently, based on the conservation of momentum in the x-direction:

m₁ ₓ v₁ ₓ cos180° + m₂ ₓ v₂ ₓ cos60° + m₃ ₓ v₃ ₓ cos(-60°) = 0

m₁ ₓ 575m/s ₓ cos180° + 4.5 x 10-3 kg ₓ 324 m/s ₓ cos60° + 4.5 x 10-3 kg ₓ 324 m/s ₓ cos(-60°) = 0

-m1 ₓ 575m/s + 1.458 ₓ 0.5 + 1.458 ₓ 0.5 = 0

-m1 ₓ 575m/s + 0.729 + 0.729 = 0

What is the minimum energy needed to change the speed of a 1600-kg sport utility vehicle from 15. 0 m/s to 40. 0 m/s?.

Answers

The power required to change a sport utility vehicle's speed is 2725 Watt.

What is speed?

A measure of how quickly an object's location can shift in any direction. Speed is defined as the distance traveled divided by the time required to cover that distance. It is a scalar because speed only has a directions and no magnitude. In common usage and kinematics, the speed of an object is a scalar quantity and is defined as the amount of the change within this object's motion per unit of time or over time.

How do you calculate the speed and its measurement?

Speed is calculated as follows: speed = distance * time. Knowing the units for distance and time is necessary to calculate the units for speed. The units will be in metres per second (m/s) in this example since the distance is measured in metres (m) and the time is measured in seconds (s).

Speed is a unit of measurement for how quickly something is moving. The most popular speed measurements are miles per hour (mph), kilometers per hour (km/h), and metres per second (m/s).

Briefing:

Mass of the sport utility = 1600kg

Initial velocity (v1) - 15m/s, (152 = 225)

Final velocity (v2) - 40m/s, ( 402 = 1600)

To find the energy required, Kinetic energy (K.E) = 1/2 mv2

K.E = final K.E - initial K.E

= 1/2(v2-v1)

= 1/2×1600×(1600-225)

= 80 × 1375

A boy of mass 70kg climbed a hill 1000m high. Calculate the maximum energy gain by the boy

Answers

The maximum energy gain of the boy can be calculated by multiplying his mass (70kg) by the gravitational acceleration (9.81 m/s^2) and the height of the hill (1000m), which gives a value of 686700 J or 686.7 kJ.

The formula E = mgh, where E is the energy gain, m is the boy's mass, g is the acceleration from gravity, and h is the height of the hill, may be used to determine the boy's maximum energy gain. In this instance, the youngster weighs 70 kg, the acceleration caused by gravity is 9.81 m/s^2, and the slope is 1000 metres high. The formula yields E = 70 kg x 9.81 m/s^2 x 1000 m = 686700 J or 686.7 kJ when we insert these numbers. This indicates that throughout his ascent of the hill, the youngster expended a total of 686.7 kilojoules of energy.

1.  a) no charge

2. a) a transverse wave

3. d) all of the above.

4. a) greater than that of radio waves.

5. b) lower than that of radio waves.

6. d) all of the above.

7. d) all of the above.

8. d) all of the above

9. a) exist for all particles

10. a) modifies classical results

11.  b) the returnee is younger

12. d) all of the above statements are correct.

1. An electromagnetic wave consists of oscillating electric and magnetic fields that propagate through space. It does not carry any net charge.

2. Electromagnetic waves are transverse waves, meaning that the direction of the electric and magnetic fields is perpendicular to the direction of wave propagation.

3. Light exhibits both wave-like and particle-like behavior, as described by the wave-particle duality principle in quantum mechanics.

4. Gamma rays have a higher frequency than radio waves, which means they have more oscillations per unit of time.

5. Gamma rays have a shorter wavelength than radio waves, indicating that the distance between successive wave crests is smaller.

6. When a tree is located 20 meters from a convex lens with a focal length of 10 cm, the image formed is inverted (upside down), diminished (smaller in size compared to the object), and real (can be projected on a screen).

7. An arrow placed 2 cm from a convex lens with a focal length of 5 cm will produce an erect (upright), virtual (cannot be projected on a screen), and magnified (larger in size compared to the object) image.

8. A parabolic mirror, such as a parabolic reflector or a parabolic antenna, has the property of focusing all parallel rays of light (or electromagnetic waves) to a single point called the focus. It also reflects rays originating from the focus in a parallel direction, which is useful for applications like satellite dish antennas. Furthermore, parabolic mirrors can work for a wide range of electromagnetic waves, including radio waves.

9. De Broglie waves, proposed by Louis de Broglie, suggest that particles, such as electrons and protons, exhibit wave-like properties. They are not limited to sound waves or specific particles like hydrogen. De Broglie waves play a crucial role in understanding the wave-particle duality of matter.

10. The Lorentz factor, denoted as γ (gamma), is a term in special relativity. It modifies classical results as objects approach the speed of light, accounting for time dilation, length contraction, and relativistic mass increase. It is a key factor in understanding the effects of high-speed motion and is not limited to geometric optics.

11. In the Twin Paradox scenario, the traveling twin experiences time dilation due to their high velocity, causing them to age slower compared to the twin who stays at home. Thus, when they reunite, (b) the returnee is younger. This phenomenon is a consequence of special relativity and has been confirmed by experiments and observations.

12. Bohr's atomic model describes electrons in discrete energy levels or orbits. According to the model, electrons can jump to lower orbits, emitting photons in the process. They can also spontaneously jump to higher orbits. Additionally, the model suggests that the electron orbit would eventually decay, resulting in the electron spiraling into the proton. However, this aspect is not consistent with modern understanding and is considered a limitation of Bohr's model.

The both cars meet at time = 4s

What is the position - time graph?

The position time graph shows the rate at which the position of a body is changing with time. The position of the body is plotted on the vertical axis and the time taken is plotted on the horizontal axis.

We can know how fast the object is going by taking the slope of the position time graph. This is known as the speed of the object. If we look keenly as the graph as we have it we can see that;

1) Speed of the black car = 10 - 0/ 1 - 0 = 10 m/s

2) Speed of the red car = 25 - 80/ 7 - 0 = -7.9 m/s

What is effect on the period of oscillation if the mass attached to the horizontal spring is increased from 0.050 kg to 0.100 kg? 2. What is effect on the period of oscillation if you are increase the mass of the bob from 0.100 kg to 0.300 kg? 3. For a pendulum bob that is swinging back and forth, at which positions is the pendulum bob temporarily stops its motion? Explain why this is happening.

Answers

If the mass attached to the horizontal spring is increased from 0.050 kg to 0.100 kg, the period of oscillation will increase.

This is because the period of an oscillating mass-spring system is inversely proportional to the square root of the mass. As the mass increases, the restoring force provided by the spring becomes stronger, resulting in a slower oscillation and a longer period.

If the mass of the bob in a pendulum is increased from 0.100 kg to 0.300 kg, the period of oscillation will also increase. The period of a pendulum is directly proportional to the square root of the length and inversely proportional to the square root of the acceleration due to gravity. Increasing the mass of the bob without changing the other parameters increases the effective length of the pendulum, which leads to a longer period.

In a swinging pendulum, the bob temporarily stops its motion at the extreme points of its swing, known as the endpoints or the highest and lowest points. This happens because at these positions, the gravitational force acting on the bob is balanced by the tension in the pendulum string or rod, resulting in a net force of zero. As a result, the bob momentarily comes to a stop before changing direction and starting its swing back. This is similar to an object momentarily pausing at the highest point of its trajectory in a projectile motion due to zero vertical velocity.
