What does the path of an object look like when it is in uniform motion?

View solution

A uniform spherical shell of mass and radius rotates about a vertical axis on frictionless bearing. A massless cord passes around the equator of the shell, over a pulley of rotational inertia and radius and is attached to a small object of mass that is otherwise free to fall under the influence of gravity. There is no friction of pulley's axle; the cord does not slip on the pulley. What is the speed of the object after it has fallen a distance from rest? Use work-energy considerations.
