Find the maximum velocity possible for the person on the swing.
if someone could explain with work that would be very much appreciated since I wasn't there when this was discussed in class.
Answer:
The maximum possible speed is 4.85 m/s.
Explanation:
The Principle Of Conservation Of Mechanical Energy
In the absence of friction, the total mechanical energy is conserved. It means that :
\(E_m=U+K\) is constant, being U the potential energy and K the kinetic energy
U=mgh
Where m is the mass of the object, g is the gravitational acceleration and h is the height from a fixed reference.
\(\displaystyle K=\frac{mv^2}{2}\)
Where v is the speed.
When the person is at a maximum height of 2 meters, the speed is 0. Thus the mechanical energy is made only of potential energy.
Let's fix the reference for the height to the point where the person is at minimum height (1 m from the ground level). The maximum height with respect to this reference is h=2.2 m - 1 m = 1.2 m.
The potential energy is:
U = m*9.8*1.2
U = 11.76m
When the person is at the minimum (zero) height, the mechanical energy is made only of kinetic energy. Since the mechanical energy is conserved, then:
\(\displaystyle \frac{mv^2}{2}=11.76m\)
Multiplying by 2 and simplifying by m:
\(v^2=2*11.76=23.52\)
Solving for v:
\(v=\sqrt{23.52}=4.85\)
\(\boxed{v=4.85}\)
The maximum possible speed is 4.85 m/s.

There is an apple with a mass of 14 kg that is attached to the tree 12
m above the ground (on earth). How much Gravitational Potential
Energy does the apple have? (Round to the nearest tenth)
Hint g= 9.8 (m/s^2)
*
Answer:
\(\boxed {\boxed {\sf 1646.4 \ J }}\)
Explanation:
Gravitation potential energy can be found using this formula:
\(E_P=m*g*h\)
where m is the mass, g is the gravtiational acceleration, and h is the height.
The mass of the apple is 14 kilograms and it is 12 meters above the ground. Since this is on Earth, the acceleration due to gravity is 9.8 m/s².
\(m= 14 \ kg \\g= 9.8 \ m/s^2 \\h= 12 \ m\)
Substitute the values into the formula.
\(E_p= ( 14 \ kg )( 9.8 \ m/s^2)(12 \ m)\)
Multiply.
\(E_p= (137.2 \ kg*m/s^2)(12 \ m )\)
Multiply again.
\(E_P= 1646.4 \ kg*m^2/s^2\)
1 kg*m²/s² is equal to 1 Joule. Our answer of 1646.4 kg*m²/s² is equal to 1646.4 Joules\(E_p=1646.4 \ J\)
This is already rounded to the tenth place, so it's the final answer.
The apple has 1,646.4 Joules of gravitational potential energy.

Calculate the load arm and effort arm from the following figure if the lever is in
balanced condition. In which class of lever do spoon and scissor belong to.(Ans: 3m, 15 m)2+1
Answer:
The length of the load arm is 3 m
The length of the effort arm is 15 m
Spoons and scissors are class 1 levers
Explanation:
The data given in the force diagram of the lever (machine) are;
The length of the lever = 18 m = (Length of effort arm) + (Length of load arm)
The force applied at the effort = 100 N
The load lifted by the lever = 500 N
The mechanical advantage, MA is given as follows;
MA = Load/Effort = (Length of effort arm)/(Length of load arm)
∴ MA = 500 N/(100 N) = 5
Let 'x' represent the length of the effort arm, and let 'y', represent the length of the load arm, we have;
x + y = 18...(1) (given)
MA = 5 = x/y
∴ x = 5·y...(2)
Substituting the value of 'x' in equation (1) with x = 5·y gives;
x + y = 5·y + y = 6·y = 18
∴ y = 18/6 = 3
y = 3
The length of the load arm, y = 3 m
x = 5·y = 5 × 3 = 15
x = 15
The length of the effort arm, x = 15 m
When lifting food with a spoon, the fulcrum, which can be taken as the edge of the plate or the supporting finger, is in between bowl of the spoon and the point of application of the thumb towards the extremities of the spoon handle
Therefore a spoon is a class 1 lever
The pivot of a scissors is in between the item being cut (the load) and the holes where the finger applies an effort
Therefore, a scissors is a class 1 lever.

a bicycle racer sprints at the end of a race to clinch a victory. the racer has an initial velocity of 11.5 m/s when he was 300 m away from the finish line. he accelerates at the rate of 0.500 m/s/s for 7.00 s; and then the racer continues at the final velocity to the finish line. (a) what is his final velocity?
As a result, the racer's final velocity is 13.00 m/s after accelerating at 0.500 m/s2 for 7.00 s.
What is velocity?Velocity is a vector representation of an object's or particle's displacement with respect to time. The meter per second (m/s) is the standard unit of velocity magnitude (also known as speed). Alternatively, velocity magnitude can be expressed in centimeters per second (cm/s). The direction of movement of the body or item is defined by velocity. Speed is fundamentally a scalar number. Velocity is, in essence, a vector quantity. It is the pace at which distance changes. It is the displacement rate of change.
Here,
The final velocity can be found using the equation of motion,
vf = vi + at,
where vf is the final velocity, vi is the initial velocity (11.5 m/s), a is the acceleration (0.500 m/s^2), and t is the time for which the acceleration was applied (7.00 s).
Substituting the values we get,
vf = 11.5 + 0.500 * 7.00 = 13.00 m/s.
So, the racer's final velocity is 13.00 m/s as he accelerates at the rate of 0.500 m/s2 for 7.00 s.

What force is necessary to pull a 10 kg sled across a horizontal surface at a constant velocity if the coefficient of kinetic friction between the sled and the ground is 0.25?
Answer:
Any force greater than 24.5 N
Explanation:
To find the frictional force is the 1st step. this can be found by multiplying the coefficient of friction and the normal force. normal force can be found by multiplying gravity (we will say 9.8 m/s/s) and the mass which is 10. You then multiply the result by the coefficient of friction which is 0.25 and it leads us to an answer to 24.5 N. This means that if you pull with exactly 24.5 N, the sled wouldnt move. So you need a force greater than 24.5 N and we have our answer.
I hope I helped correct me if im wrong
A force of 25 N is necessary to pull a 10 kg sled across a horizontal surface at a constant velocity if the coefficient of kinetic friction between the sled and the ground is 0.25.
First, we will calculate the normal force (N), which, in a horizontal surface, has the same magnitude and opposite sense as the weight (W) of the sled.
\(|N| = |W| = m \times g = 10 kg \times \frac{9.8m}{s^{2} } = 98 N\)
where,
m: mass of the sledg: Earth's gravityThen, we will calculate the friction force (f) using the following expression.
\(f = \mu \times N = 0.25 \times 98 N = 25 N\)
According to Newton's first law of motion, for the sled to move at a constant velocity, the sum of the force exerted (F) on the sled and the friction force (f) must be zero.
\(F + f = 0\\F = -f\\F = -25 N\\|F| = 25 N\)
A force of 25 N is necessary to pull a 10 kg sled across a horizontal surface at a constant velocity if the coefficient of kinetic friction between the sled and the ground is 0.25.

A 12 kg mass, moving at 16 m/s, experiences an opposing force of 18 n for 3. 0 s. What is the magnitude of the change in momentum of the object?.
The momentum of an object is the product of its mass and velocity. If the object is moving with a certain velocity and an external force is applied on it then there is a change in the momentum of the object.
The formula for calculating impulse is FΔt, where F is the force and Δt is the time for which the force acts on the object. The impulse acting on the object is equal to the change in momentum of the object.
The time for which the force acts on the object is Δt = 3.0 s. Therefore, the magnitude of the change in momentum of the object is 54 kg m/s. The impulse acting on the object is also 54 N s.

a 3.0 hz continuous wave travels on a slinky. if the wavelength is 0.57 m, what is the speed of waves on the slinky (in m/s)? m/s
If the wavelength is 0.57 m, then the speed of waves on the slinky is 1.71 m/s.
The speed of waves on the slinky (in m/s) for a 3.0 Hz continuous wave that travels on a slinky with a wavelength of 0.57 m can be calculated by multiplying the frequency of the wave by its wavelength. Mathematically, it can be expressed as;
Speed of waves on the slinky = Frequency × Wavelength
