A hollow sphere is released from the top of an inlcined plane of inclination `theta`. A. What should be the minimum coefficientof friction between the shphere and the plane to prevent sliding? B. Find the kinetic energy of the ball as it moves down a length l on the incline if the friction coefficient is half the value calculated in part a.
