A ball rolling without slipping along a horizontal surface comes to an incline. In which case will the ball go higher up the incline, if the inclined surface is frictionless, or has friction?
A. Friction    B. No friction    C. Same    D. Un knowable



A hollow cylinder and a solid cylinder of the same mass and radius reach the bottom of an incline rolling at the same angular speed. Add together possible true answers and enter.
1. They started rolling from the same height at rest.
2. They both started from rest, but the solid cylinder started higher up the slope.
4. They both started from rest, but the hollow cylinder started higher up the slope.
8. They both started from the same location, but the solid cylinder started with some initial velocity.
16. They both started from the same location, but the hollow cylinder started with some initial velocity.
