Assume that a 1.00kg ball is thrown solely by the action of the forearm, which rotates about the elbow joint under the action of the triceps muscle. The ball is accelerated uniformly from rest to 10.0 m/s in .350s at which point it is released. Calculate the angular acceleration of the arm and the force required of the triceps muscle. Assume that the forearm has a mass of 3.70kg and rotates like a uniform rod about an axis at its end.
