A cue ball initiallymoving at 4.3m/s strikes
a stationary eight ball of the same size and
mass. After the collision, the cue ball’s final
speed is 2 m/s .Find the cue ball’s angle with respect to
its original line of motion. Consider this to
be an elastic collision (ignoring friction and
rotational motion).
Answer in units of degrees.

A billiard ball moving at 5.00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.33 m/s, at an angle of 30.0 degrees with respect to the original line of motion. Assuming an elestic collision (and ignoring friction and rotational motion), find the struck ball's velocity after collision.

Jeanette is playing in a 9-ball pool tournament. She will win if she sinks the 9-ball from the final rack, so she needs to line up her shot precisely. Both the cue ball and the 9-ball have mass m, and the cue ball is hit at an initial speed of v_i. Jeanette carefully hits the cue ball into the 9-ball off center, so that when the balls collide, they move away from each other at the same angle theta from the direction in which the cue ball was originally traveling. Furthermore, after the collision, the cue ball moves away at speed v_f, while the 9-ball moves at speed v_9

 

For the purposes of this problem, assume that the collision is perfectly elastic, neglect friction, and ignore the spinning of the balls..

 

Find the angle theta that the 9-ball travels away from the horizontal, as shown in the figure.
