the moment of inertia of a jumpers HAT Head Arms Trunk segme

the moment of inertia of a jumper\'s HAT (Head, Arms, Trunk) segment about the hip joint is 10.4 kg*m^2. If the jumper generates a 200 Nm average extension torque during the .25 secons propulsive phase, what is the angular acceleration during this time?

Solution

torque = moment of inertia)*(alpha

=> 200 = 10.4*alpha

=> alpha = 200/10.4 = 19.230 rad/s^2
