A wheel has a radius of 0. 40 m and is mounted on frictionless bearings. A block is suspended from a rope that is wound on the wheel and attached to it (see figure). The wheel is released from rest and the block descends 1. 5 m in 2. 00 s without any slipping of the rope. The tension in the rope during the descent of the block is 20 n. What is the moment of inertia of the wheel?.
