Use the worked example above to help you solve this problem. Two billiard balls of identical mass move toward each other as shown in the figure. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are
v1i = +25.2 cm/s
and
v2i = ?20.1 cm/s,
what are the velocities of the balls after the collision? Assume friction and rotation are unimportant. (Indicate the direction with the sign of your answer.)
| v1f = | cm/s | ||||
| v2f = |
cm/s Find the final velocity of the two balls if the ball with velocity v2i = ?20.1 cm/s has a mass equal to half that of the ball with initial velocityv1i = +25.2 cm/s. (Indicate the direction with the sign of your answer.)

Two billiard balls, a cue ball and an eight ball, of equal mass undergo a perfectly elastic head-on collision. If the cue ball’s initial speed was 8.8 m/s, and the eight ball's was 8.3 m/s in the opposite direction, what will be the velocity of the eight ball after the collision? Consider the initial direction of the cue ball to be the positive direction.
