A billiard ball moving at 5.65 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 5.12 m/s, at an angle of 25° with respect to the original line of motion. (a) Find the velocity (magnitude and direction) of the second ball after collision. (Enter the direction with respect to the original line of motion. Include the sign of your answer. Consider the sign of the first ball's angle.) m/s (b) Was the collision inelastic or elastic? O inelastic O elastic
