In a pool game, the cue ball, which has an initial speed of5.0m/s, make an elastic collision with the eight ball, which is initially at rest. After the collision, the eight ball moves at an angle of25°to the original direction of the cue ball.
(a) Find the direction of motion of the cue ball after the collision.
° (from the original line of motion)
(b) Find the speed of each ball. Assume that the balls have equal mass.
m/s (cue ball)
m/s (eight ball)
