1. A pool player makes a shot on a pool table. The 0.17 kg cue ball strikes the 0.15 kg #8-ball, but it is not sunken on the table. Instead, the 8-ball bounces off a rail, and collides into the cue ball a second time. When they collide in a perfectly elastic collision, the cue ball is travelling 1.2 m/s [N10'E] and the 8-ball is travelling 0.89 m/s [W20'N]. Determine the final velocities of each ball. (10 Marks)
