A billiard ball moving at 5.60 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.99 m/s, at an angle of 27.0 with respect to the original line of motion. (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.)
(a) Find the velocity (magnitude and direction) of the second ball after collision.
