Question: A uniform hollow disk has two pieces of thin light wire wrapped around its outer rim and is supported from the cei1ing (Fig. 10.51). Suddenly

A uniform hollow disk has two pieces of thin light wire wrapped around its outer rim and is supported from the cei1ing (Fig. 10.51). Suddenly one of the wires breaks and the remaining wire does not slip as the disk rolls down. Use energy conservation to find the speed of the center of this disk after it has fallen a distance of 1.20 m.
