A superball of mass 50 g is dropped from a height of 10 cm. (Since it is a superball, assume that it rebounds from the surface with the same velocity with which it hit the surface.) If the superball was in contact with the table for 28 ms, calculate the average force exerted on the ball by the table. Show your work. (Hint: First calculate the momentum before and after hitting the table. Don't forget the gravitational force. N
The superball is now replaced with a clay ball that has the same mass and is dropped from the same height. What would be the average force exerted on the clay ball?
Explain why these two forces are different.
If the mass of the superball were doubled, what would you expect to happen to the force? Explain.
If the height of the original super were doubled, what would you expect to happen to the force, and why?
