A basketball (which can be closely modelled as a hollow spherical shell) rolls down a mountainside into a valley and then up the opposite side, starting from rest at a height H0 above the bottom. In Fig. P10.73, the rough part of the terrain prevents slipping while the
smooth part has no friction. Neglect rolling friction and assume the system’s total mechanical energy is conserved. (a) How high, in terms of H0, will the ball go up the other side? (b) Why doesn’t the ball return to height H0? Has it lost any of its original potential energy?
