1. The problem statement, all variables and given/known data This is a question I have for a presentation on rotational motion: "A solid cylinder rolls down an incline faster than a hoop [or say an open cylinder], whether or not they have the same mass or diameter. The hoop has greater rotational inertia relative to its mass than a cylinder does." Now my question is when they reach the bottom of the incline to a flat surface, which one will roll the farthest? (if their masses are the same) Suppose the amount of friction and air resistance are the same for both. 2. Relevant equations 3. The attempt at a solution I'm guessing that the hoop will since it has greater rotational inertia to keep it rolling, but another professor thinks it may be the solid cylinder.
