The height to which a ball bounces after being dropped provides a measure of how much energy is lost in the collision with the floor or other surface. A small portion of energy is lost to air resistance as the ball is moving, but most is lost in the collision.

1. Trying a number of different balls that you that you may have available, test the height of the bounce using the same height or release for all of the balls tested. Which ball loses the most energy and which is the least?

2. Can you explain why many balls return to a higher height than a marble will? What characteristics of the balls tested give the best bounce?

3. For a ball that bounces several times, does the period (time between bounces) change with each bounce? (Again, recording a video would help tremendously. Make sure your camera is held still and a meter stick or some other object of known height is within the frame, but does not obstruct the motion)

4. Can you predict how the bounce height would change if your release height is doubled? Halved?

5. Try it, observe, measure and record your results. 6. Does the bouncing ball undergo simple harmonic motion? Why or why not?

A ball, dropped onto a hard floor from a height of 2 meters, bounces to a...

A ball, dropped onto a hard floor from a height of 2 meters, bounces to a height of 1.8 meters, 90% of the initial height. Each subsequent bounce is 90% the height of the previous one. Find the total distance the ball travels up and down (i.e. after the first collision with the ground it has traveled 2 meters down and 1.8 meters up, giving a total distance of 3.8 meters).

A 200-g ball is dropped from rest from a height of 1.4 m. It bounces and returns to the same position. a) What is the change in momentum between the two points? b) If the ball is in contact with the floor for 10-3 s, what impulse does the floor impart to the ball? In these cases remember vectors.

1)A 861 g rubber ball is dropped from height 15.1 m, and it rebounds to height 3.15 m. Assuming there is no air friction, find the magnitude of the impulse, in N-s, exerted by the ground on the ball. 2)Milly (mass 98.7 kg) runs at 2.73 m/s along the positive x-axis and then jumps onto a stationary 278 kg box. Milly and the box slide across the floor for distance 0.357 m, and then they come to a stop. Find...

A rubber ball is dropped from a height of 30 feet, and on each bounce it rebounds up 22% of its previous height. How far has the ball traveled vertically at the moment when it hits the ground for the 23rd time? Round your answer to two decimal places.

If a golf ball were dropped from a significant height and the force of Drag is...

If a golf ball were dropped from a significant height and the force of Drag is modeled by Fd=0.0057*V-0.0106, where V is the velocity in m/s the Fd is the force of drag in N. The mass of the golf ball is 0.0455 Kg. h. How high will the golf ball bounce after the 5th impact with the concrete surface ignore drag force? i. If drag was included for G and H what type of analysis technique would be needed

A steel ball with a mass of 0.600 kg is dropped from an initial height of 2.80 m onto a metal plate. The steel ball bounces multiple times and on each bounce it returns to 75% of its previous maximum height. A)What is the initial mechanical energy of the ball-Earth system, just after the ball is released from its initial height? Use the surface of the steel plate as the y = 0 reference point for the gravitational potential energy....
