Question

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 20.0 m/s at a distance of 0.480 m from the joint and the moment of inertia of the forearm is 0.500 kg⋅m^2, what is the rotational kinetic energy of the forearm?

Step 1

0 m/s) and r is the distance of the ball from the joint (0.480 m). omega = 20.0 m/s / 0.480 m omega = 41.67 rad/s Show more…
