Q. The flywheel of an engine has a moment of inertia 2.40 kg m^2 about its rotation axis. What constant torque is required to bring it up to an angular speed of 400 rev/min in a time of 8.50 s, starting from rest? What is its final kinetic energy?

Q. A sanding disk with rotational inertia 8.1 x 10-3 kg·m2 is attached to an electric drill whose motor delivers a torque of magnitude 20 N·m about the central axis of the disk. About that axis and with torque applied for 29 ms, what is the magnitude of the (a) angular momentum and (b) angular velocity of the disk?
