1. A uniform sperical shell of mass Ms and radius R rotates about a vertical axis on frictionless bearings. A light cord passes around the equator of the shell over a pulley (a disk of mass Mp and radius r) and is attached to a small block of mass m that is otherwise free to fall under the influence of gravity.
A. What is the acceleration of the block?
B. What is the tension force acting on the block?
C. What is the tension force acting on the sphere?
