1. The problem statement, all variables and given/known data A flywheel of mass 181 kg has an effective radius of 0.63 m (assume the mass is concentrated along a circumference located at the effective radius of the flywheel). (a) What torque is required to bring this wheel from rest to a speed of 118 rpm in a time interval of 29.4 s? _____ N·m (b) How much work is done during the 29.4 s? ______ kJ 2. Relevant equations ?????????? 3. The attempt at a solution How is this problem done when time is involved?? I am confused. I have done I = mr^2 and thats it.
