A base-ball pitcher pivots his extended arm around his shoulder joint, applying a constant torque of 199 N • m for 0.16 s to his arm, which consists of a moment of inertia of 0.53 kg • m2.
(i) Determine his arm's angular acceleration and final angular velocity, supposing it begins from rest.
(ii) Determine the final speed of the ball, relative to the shoulder, which is 0.79 m from the ball.
