The figure gives an overhead view of the path taken by a 0.160 kg cue ball as it bounces from a rail of a pool table. The ball’s initial speed is 2.63 m/s, and the angle θ1 is 57.5°. The bounce reverses the y component of the ball’s velocity but does not alter the x component. What are (a) angle θ2 and (b) the magnitude of the change in the ball’s linear momentum? (The fact that the ball rolls is irrelevant to the problem.)
