Solution
... When the ball has rolled to the lowest point, potential energy U = mgh has been converted to kinetic energy of translation and rotation. When the ball moves up on the other side, it will remain spinning at constant angular speed as there is no friction to decrease the angular speed. Thus, only the k ...

Notice that when the forces are balanced, the object might still be moving, but the objects are not accelerating, instead they have a constant velocity. Hence, once in motion – it’s always in motion ...
