A sanding disk with rotational inertia 8.2 x 10-3 kg·m2 is attached to an electric drill whose motor delivers a torque of magnitude 14 N·m about the central axis of the disk. About that axis and with torque applied for 54 ms, what is the magnitude of the (a) angular momentum and (b) angular velocity of the disk?
