The figure gives an overhead view of the path taken by a 0.169 kg cue ball as it bounces from a rail of a pool table. The ball's initial speed is 1.32 m/s, and the angle 0 is 63.6. The bounce reverses the y component of the ball's velocity but does not alter the x component. What are (a) angle 82 and (b) the magnitude of the change in the ball's linear momentum? (The fact that the ball rolls is irrelevant to the problem.)
