A flywheel of mass 196 kg has an effective radius of 0.620 m (assume that the mass is concentrated along a circumference located at the effective radius of the flywheel). Question 1: How much work is required to bring this wheel from rest to an angular speed of 134 rev/min in a time interval of 30.0 s? (in kJ)
Question 2: What constant torque is required to bring the wheel from rest to an angular speed of 134 rev/min in a time interval of 30.0 s? (in N*m)
