QUESTION NO. 4:
Figure 4 gives an overhead view of the path taken by a 0.165 kg cue ball as it bounces from a
rail of a pool table. The ball's initial speed is 2.0 m/s, and the angle 0, is 30.0°.The bounce
reverses the y component of the ball's velocity but does not alter the r component. If the ball
is in contact with the wall for 10 ms, what are?
(a) the initial and final velocities in unit-vector notations?
(b) angle 0,7
(e) the impulse on the ball from the wall?
(d) the average force on the ball by the wall?
