Question
a circular hoop of mass and radius spins like a wheel rotating about its centre with moment of inertia. its period it T
(1) find the kinetic energy in terms of the given parameters
2. if such a hoop rolls with its centre moving at velocity v show that it rolls down an inclined plane with half the acceleration that a frictionless sliding block would have
