Question

In the game of billiards, all the balls have approximately the same mass, about 0.17 kg. In the figure, the cue ball strikes another ball that is at rest, such that it follows the path shown. The other ball has a speed of 1.5 m/s immediately after the collision. a.) What is the kinetic energy of the cue ball after the collision? b.) Is the collision elastic or inelastic?

3.0 m/s 30.0° O 60.0° 1.5 m/s

    A “pool shark” takes aim at the eight ball in a game of billiards. Her shot gives the cue ball a velocity of 2.5 m/s [forward]. The cue ball strikes the eight ball and continues with a velocity of 0.25 m/s [forward]. If the mass of both the cue ball and the eight ball equals 400 g, calculate the velocity of the eight ball after collision.

    A cue ball strikes two billiard balls at rest simultaneously with a speed of 8.0 m/s. Immediately after the collision, the cue ball stops in place, while one of the other balls moves with a velocity of 5.0 m/s at 20 degree from the cue ball's line of action. If the other ball that was struck moves at 30 degree in the direction illustrated, and all three balls have equal mass, find the post-collision speed V_2 of the second ball.
