In a pool game, the cue ball, which has an initial speed of 3.0 m/s, make an elastic collision with the eight ball, which is initially at rest. after the collision, the eight ball moves at an angle of 40° 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)
