In Sharkey's Billiard Academy, Maurice is waiting to make his last shot. He notices that the cue ball is lined up for a perfect head-on collision, as shown.
Each of the balls has a mass of 0.0800 kg and the cue ball comes to a complete
stop upon making contact with the 8 ball. Suppose Maurice hits the cue ball
by exerting a force of 180. N for 5.00 X 10 -3 s, and it knocks head-on into the
8 ball. Calculate the resulting velocity of the 8 ball.
