A 1.25 kg pendulum bob suspended from a 0.5-m cable, is released from rest at an angle θ as shown. It then creates a head-on collision with a 0.625-kg stationary basketball that bounces off with a speed of vB’ = 1.657 m/s. If the coefficient of restitution between the bob and the ball is 0.75, determine:
a. the angle ? to where the bob is released.
b. the average impulsive force (N) exerted by the bob on the ball if the collision occurred in 0.001 s.
