Rotational dynamics: Putting it all together

Bowling At the start of your throw of a 2.7-kg bowling ball, your arm is straight behind you and horizontal (Figure P8.66). Determine the rotational acceleration of your arm if the muscle is relaxed. Your arm is 0.64 m long, has a rotational inertia of 0.48 kg . m², and has a mass of 3.5 kg with its center of mass 0.28 m from your shoulder joint.
