The angular momentum of a flywheel having a rotational inertiaof 0.407 kg·m2 about its central axis decreases from5.40 to 0.970 kg·m2/s in 4.60 s. (a)What is the magnitude of the average torque acting on the flywheelabout its central axis during this period? (b)Assuming a constant angular acceleration, through what angle doesthe flywheel turn? (c) How much work is done onthe wheel? (d) What is the magnitude of theaverage power done on the flywheel?
