A uniform circular cylinder (a yo-yo) has a light inextensible string wrapped around it so that it does not slip. The free end of the string is secured to a fixed point and the yo-yo descends in a vertical straight line with the straight part of the string also vertical.

Explain why the string does no work on the yo-yo. Find the energy conservation equation for the yo-yo and deduce its acceleration.
