##### Reference no: EM13490373

A ball having a mass of 170 g strikes a wall with a speed of 5.0 m/s and rebounds with only 50% of its 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 the ball?

____N·s

(c) If the ball was in contact with the wall for 7.4 ms, what was the magnitude of the average force exerted by the wall on the ball during this time interval?

____N
