The ball A travels with a velocity of va (given below) just before it strikes the ball B which is at rest. The masses of A and B are each 200 g, and the coefficient of restitution between them is e (given below). Neglect friction in the system. a) Determine the speeds of the balls just after the impact. (Draw the final velocity vectors!) b) Draw the impulse-momentum diagram of each ball. (Separately!) c) Determine the interaction time during which the impact occurs if the average force exerted between the balls is 500 N. (Hint: Apply the impulse-momentum principle to one of the balls!) VA
