Two billiards balls are resting on a smooth table, and just touching. A third identical ball moving along the table with velocity v perpendicular to their line of centres strikes both balls simultaneously. Find the velocities of the three balls immediately after impoact, assuming that the collision is elastic.

63. Two billiard balls of identical mass move toward each other. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are 30 cm/s and -20 cm/s, assume friction and rotation are unimportant What are the velocities of the balls after the collision? Find the final velocity of the two balls if the ball initial velocity of -20 cm/s has a mass equal to one half of the ball with initial velocity 30 cm/s

2- Two identical billiard balls may move freely on a horizontal table. Ball A has a velocity of 0.4 m/s as shown, and hits ball B, which is at rest, at point C defined by ? = 40° (the line of impact is along 40° path with respect to the horizontal direction). Assuming no friction, and knowing the coefficient of restitution between the two balls is 0.75, determine the velocity of each ball after impact.

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...
