 3. A solid sphere (mass mi = 2.5 kg, radius ri

3. A solid sphere (mass mi = 2.5 kg, radius ri = 0.20 m) rotates about a horizontal axis on frictionless bearings. A massless cord passes around the equator of the sphere, over a pulley (mass m2 = 2.0 kg, radius r2 = 0.30 m), and is attached to a block (mass my = 3.0 kg) that is otherwise free to fall under the influence of gravity. The block is released from rest; what is the speed of the block after it has moved 1.0 m? pulley (disk) m2, 12 solid sphere 13
