A flywheel of mass 185 kg has an effective radius of 0.60 m (assume the mass is concentrated along a circumference located at the effective radius of the flywheel). (a) How much work is done to bring this wheel from rest to a speed of 120 rpm in a time interval of 35.0 s? (in kg please) (b) What is the applied torque on the flywheel (assumed constant)? (in N * m please)
