A sanding disk with rotational inertia 4.6x 10 kg-m? is attached to an electric dill whose motor delivers a torque of magnitude 40N-m about the central axis of the disk. About that axis and with torque applied for 46 ms, what is the magnitude of the (a) angularmomentum and (b) angular velocity of the disk? Calculate the rotational inertia of a meter stick, with mass 0.418 kg, about an axis perpendicular to the stick and located at the 17.8 cmmark. (Treat the stick as a thin rod.)
