    A uniform hollow disk has two pieces of thin light wire wrapped around its outer rim and is supported from the ceiling (See figure). Suddenly one of the wires breaks, and the remaining wire does not slip as the disk rolls down. The inner radius of the cylinder is 30 cm and the outer radius is 50 cm. Use energy conservation to find the speed of the center of this disk after it has fallen a distance of 2.20 m.
