Exercise 6.2:
4. A ball moving with a speed of 17 m s-¹ strikes an identical ball
that is initially at rest. After the collision, the incoming ball has
been deviated by 45° from its original direction, and the struck
ball moves off at 30° from the original direction as shown in
Figure 3.17. Calculate the speed of each ball after the collision.
