A ball having a mass of150 g strikes a wall with a speed of4.8 m/s and rebounds with only 50% ofits initial kinetic energy.
(a) What is the speed of the ball immediately after rebounding?
m/s
(b) What is the magnitude of the impulse on the wall from theball?
Ns
(c) If the ball was in contact with the wall for 8.0 ms, what was the magnitude of the averageforce exerted by the wall on the ball during this timeinterval?
N
