Three objects, A: (a solid sphere), B: (a thin circular disk) and C: (a circular ring), each have the same mass and radius They all spin with the same angular speed about their own symmetry axes. The amounts of work (W) required to bring them to rest, would satisfy the relation
To solve this problem, we need to calculate the work done to bring each object to rest.The work done is equal to the change in kinetic energy, which is given by:
