Question:

A ball having a mass of 1-50 g strikes a wall with a speed of 5.2m/s and rebounds with only 50% of its initial kinetic energy.

(a) What is the speed of the ball immediately after rebounding?

(b) What is the magnitude of the impulse on the wall from the ball?

(c) If the ball is in contact with the wall for 7.6 ms, what is the magnitude of the average force on the ball from the wall during this time interval?
