A billiard ball moving at 5. 00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves, at 4. 33 m/s, at an angle of 30. 0° with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball’s velocity after the collision.
