Question
The triceps muscle in the back of the upper arm extends the forearm. This muscle in a professional boxer exerts a force of 2.00X10^3 N with an effective perpendicular lever arm of 3.00 cm, producing an angular acceleration of the forearm of 120 rad/s^2 .What is the moment of inertia of the boxer's forearm?

torque applied = 2000 * 0.03 = 60 N-m
inertia * 120 = toque = 60
so inertia = 0.5 kg / m^2
