A billiard ball moving at 530 ms strikes a stationary ball, Ask an Expert

Academics

A billiard ball moving at 5.30 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.72 m/s, at an angle of 27.0° with respect to the original line of motion.

(a) Find the velocity (magnitude and direction) of the second ball after collision.

m/s

° (with respect to the original line of motion, include the sign of your answer; consider the sign of the first ball's angle)

(b) Was the collision inelastic or elastic?

inelastic

elastic
