A baseball 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 13.0 m/s at a distance of 0.380 m from thejoint and the moment of inertia of the forearm is 0.5 kg - m2, what is the rotational kinetic energy, in joules, of the forearm? :1
