In Figure P11.51, a cue ball is shot toward the eight-ball on a pool table. The cue ball is shot at the eight-ball with a speed of 8.00 m/s in a direction 30.0° from the y axis. Both balls have the same mass of 0.170 kg. After the balls undergo an elastic collision, the eight-ball travels in the negative x direction into the side pocket. What is the velocity of the cue ball after this collision?

A cue ball traveling at 4.0 m/s makes a glancing, elastic collision with a target ball of equal mass that is initially at rest. The cue ball is deflected so that it makes an angle of 30° with its original direction of travel. (a) Find the angle between the velocity vectors of the two balls after the collision.(b) Find the speed of each ball after the collision

Jeanette is playing in a 9-ball pool tournament. She will win ifshe sinks the 9-ball from the final rack, so she needs to line upher 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. Jeanettecarefully hits the cue ball into the 9-ball off center, so thatwhen the balls collide, they move away from each other at the sameangle theta from the direction in which the cue ball was originallytraveling (see figure). Furthermore, after the collision, the cueball moves away at speed v_f, while the 9-ball moves at speedv_9.

For the purposes of this problem, assume that the collision isperfectly elastic, neglect friction, and ignore the spinning of theballs
Find the angle theta through which the 9-ball travels away from thehorizontal, as shown in the figure. Perhaps surprisingly, youshould be able to obtain an expression that is independent of anyof the given variables!
Express your answer in degrees to three significant figures.

A cue ball of mass m1 = 0.325 kg is shot at another billiard ball, with mass m2 = 0.505 kg, which is at rest. The cue ball has an initial speed of v = 7.5 m/s in the positive direction. Assume that the collision is elastic and exactly head-on.

(a) What is the horizontal component of the billiard ball's velocity, v2f, after the collision, in meters per second?

(b) What is the horizontal component of the cue ball's final velocity, v1f, in meters per second?
