A tennis ball is dropped from 1. 0 m, bounces off the ground, and rises to 0. 85 m. What kind of collision occurred between the ball and the ground?.
Answers
When a tennis ball is dropped from 1.0 m, bounces off the ground, and rises to 0.85 m, an inelastic collision occurs between the ball and the ground.
An inelastic collision is a type of collision in which two objects collide and stick together after the collision. The kinetic energy of the system is not conserved because some energy is lost due to friction and deformation. In this case, the tennis ball collides with the ground, and the energy is not completely conserved. Some energy is lost to heat due to the deformation of the tennis ball and the ground when they collide. The deformation of the ball and the ground is caused by the force of the collision.
When a tennis ball collides with the ground, it causes the ground to deform, and the ball also deforms. The energy of the ball is transferred to the ground, causing the ground to vibrate. Some of the energy is lost to heat due to friction, and some of the energy is lost due to the deformation of the ball and the ground. As a result, the ball bounces back up to a height of 0.85 m instead of reaching the original height of 1.0 m. Hence, an inelastic collision occurred between the ball and the ground.
To summarize, when a tennis ball is dropped from 1.0 m, bounces off the ground, and rises to 0.85 m, an inelastic collision occurs between the ball and the ground. The kinetic energy of the system is not conserved because some energy is lost due to friction and deformation.

A spring gun initially compressed 2 cm fires a 0.01 kg dart straight up into the air. If the dart reaches a height of 5.5 m, determine the spring constant of the dart gun.
Answers
The spring constant of the dart gun compressed by 2 cm is determined as 121.275 N/m.
What is the spring constant?To determine the spring constant of the dart gun, we can use the conservation of energy principle, which states that the initial potential energy stored in the compressed spring is converted to the kinetic energy of the dart and its potential energy due to its position in the gravitational field.
The initial potential energy stored in the compressed spring is given by:
U = (1/2)kx²
where;
k is the spring constant and x is the compression of the spring.In this case, x = 0.02 m.
The kinetic energy of the dart just after it leaves the spring is given by:
K = (1/2)mv²
where;
m is the mass of the dart and v is its initial velocity.Since the dart is fired straight up, its initial velocity is zero.
At the highest point of the dart's trajectory, all of its kinetic energy has been converted to potential energy due to its position in the gravitational field. The potential energy of the dart at this point is given by:
U = mgh
where;
h is the maximum height reached by the dart.Equating the initial potential energy stored in the spring to the final potential energy of the dart, we have:
(1/2)kx² = mgh
Substituting the given values, we get:
(1/2)k(0.02)² = 0.01 * 9.81 * 5.5
Solving for k, we get:
k = (0.01 x 9.81 x 5.5) / (0.02)² = 121.275 N/m

t = 12 seconds
Putting the values in the equation (1)
s = 6 X 12 + \(\frac{1}{2}\) X 2 X 144
s = 72 + 144
s = 216 m
Therefore the distance travelled is 216 m
For part 2 we need to calculate the final velocity that Paco was driving
We know that
v = u + at . . . . . . . . . . . .(2)
where v = final velocity
u = initial velocity
a = acceleration
t = time in seconds
As per the question,
u = 4m/s
a = 0.5 m/\(s^{2}\)
t = 30 seconds

For freely falling objects near earth's surface, _____ is constant.
A
acceleration
B
speed
C
velocity
D
momentum
Answers
The correct option is A. acceleration.
For freely falling objects near Earth's surface, acceleration is constant. An object that is allowed to fall freely under the influence of Earth's gravity is known as a freely falling object. Gravity is an acceleration that acts on any two masses.
For freely falling objects near Earth's surface, the acceleration is indeed constant. This fundamental concept is a result of gravity's influence on objects in free fall. When an object is in free fall, it means that no forces other than gravity are acting upon it. In this scenario, the acceleration experienced by the object remains constant and is equal to the acceleration due to gravity, which is approximately 9.8 meters per second squared (m/s²) near Earth's surface.
The constancy of acceleration in free fall can be attributed to the consistent force of gravity acting on the object. Gravity pulls objects downward towards the center of the Earth, causing them to accelerate uniformly. Regardless of the object's mass, shape, or composition, the acceleration remains constant. This is known as the equivalence principle, which states that all objects experience the same acceleration due to gravity in the absence of other forces.
As an object falls freely, its velocity increases at a steady rate. Each second, the object's velocity increases by approximately 9.8 m/s. This means that in the first second, the velocity increases by 9.8 m/s, in the second second it increases by an additional 9.8 m/s, and so on. The consistent acceleration enables the object to cover greater distances in successive time intervals.
In conclusion, for freely falling objects near Earth's surface, the acceleration remains constant at approximately 9.8 m/s². This constancy arises from the unchanging force of gravity acting on the objects, leading to a uniform increase in velocity over time.

total stopping distance is the distance a vehicle travels from the moment the driver applies the brakes until the vehicle comes to a complete stop. It consists of two main components: the thinking distance and the braking distance.
total stopping distance refers to the distance a vehicle travels from the moment the driver applies the brakes until the vehicle comes to a complete stop. It is composed of two main components: the thinking distance and the braking distance.
The thinking distance is the distance the vehicle travels during the driver's reaction time. It is the time it takes for the driver to perceive a hazard and apply the brakes. Factors that can affect the thinking distance include the driver's alertness, distractions, and the speed of the vehicle.
The braking distance is the distance the vehicle travels while the brakes are applied and the vehicle decelerates. It depends on factors such as the speed of the vehicle, the condition of the road, and the efficiency of the brakes.
Therefore, the total stopping distance is influenced by both the thinking distance and the braking distance. It is important for drivers to maintain a safe following distance and be aware of their vehicle's stopping capabilities to ensure they can stop in time to avoid collisions.

It's possible that a driver's foot isn't on the brake when they realise they need to stop the car. The car, for instance, is going at a constant speed.
The moment the driver realises that the vehicle needs to be stopped, his or her foot is moved to the brake pedal. The reaction distance is what we refer to as.

An aluminium cube of side 5cm and R.D 2.7 is suspended by a thread in alcohol of relative density 0.8o. Find the tension in thread.
Answers
Answer:
The tension in the thread is approximately 3.2103225 Newtons
Explanation:
The given parameters are;
The side length of the aluminum cube, s = 5 cm
The R.D. of aluminum = 2.7
The relative density of alcohol into which the aluminum cube is placed = 0.8
The volume of the aluminum cube, V = s³ = (5 cm)³ = 125 cm³
The mass of the aluminum cube, V = The volume of the cube
The mass of the aluminum cube, m = V × R.D. × Density of water
m₁ = 0.000125 × 2.7 × 970 = 0.327375 kg
The mass of the alcohol displaced, m₂ = 0.000125 × 0.8 × 970 = 0.097
The tension in the string, T = The apparent weight of the aluminum cube, Wₐ
∴ The tension in the thread, T = Wₐ = (m₁ - m₂) × g
Where;
g = The acceleration due to gravity ≈ 9.81 m/s²
∴ T ≈ (0.327375 - 0.000125) × 9.81 = 3.2103225
The tension in the thread, T ≈ 3.2103225 N.

In physics, we use vector addition to calculate the net force direction when more than one force is applied. Given the separate x and y components of two forces, F₁ and F₂, we sum the components respectively to find the x and y components of the net force. The arctangent of the ratio Fy/Fₓ then gives the direction in degrees relative to the x-axis.
Explanation:In physics, specifically in mechanics, you can calculate the net force direction when two forces, F₁ and F₂, are being applied by using vector addition. Vector addition can be visualized graphically using arrows or mathematically using components. In this case, since the forces are given in the form of components (x and y), let's handle it mathematically, the x-component of the net force (Fₓ) will be the sum of the x-components of F₁ and F₂. Similarly, the y-component of the net force (Fy) will be the sum of the y-components of F₁ and F₂. This gives us Fₓ = 5.01N + 3.01N and Fy = 3.0N + 2.0N.
