Abaseball pitcher throws the ball in a motion where there is rotation of the forearm about the elbow joint as well as other movements. if the linear velocity of the ball relative to the elbow joint is m/s at a distance of m from the joint and the moment of inertia of the forearm is kg·m2, what is the rotational kinetic energy of the forearm?
