A 1.40 kg mass is attached to a light cord that is wrapped around a pulley of radius 3.50 cm, which turns with negligible friction. The mass falls at a constant acceleration of 2.60 m/s2. Find the moment of inertia of the pulley.

A hollow cylinder and a solid cylinder have the same diameter. Determine which has the greater moment of inertia with respect to an axis of rotation along the axis of the cylinder.
