I've tried everything I know but I can't manage to get the question right, I need help understanding how to solve this question.

A baseball pitcher brings his arm forward during a pitch, rotating the forearm about the elbow. If the velocity of the ball in the pitcher's hand is 35.7 m/s (about 8.0 X 10 mph) and the ball is 0.310 m from the elbow joint, what is the angular velocity of the forearm? forearm angular velocity: rad/s
