A small solid sphere of mass `m` is released from point A. portion AB is sufficiently rough (to provide accelerated pure rolling) BC is smooth and after C the ball moves freely under gravity find gravitational potential energy (U), rotational kinetic energy `(K_(R))` ad translational kinetic energy `(K_(T))` at points A, B, C , D and E.
