Multiple-Concept Example 10 provides one model for solving this type of problem. Two wheels have the same mass and radius of 4.1 kg and 0.40m, respectively. One has (a) the shape of a hoop and the other has (b) the shape of a solid disk. The wheels are rolling without slipping on a horizontal surface. Which wheel has the greater rotational kinetic energy?
1) The hoop-shaped wheel
2) The solid disk-shaped wheel
