A disk, a hoop, and a sphere are released at the same time at the top of an inclined plane. They all roll without slipping. In what order do they reach the bottom?
A. disk, hoop, sphere
B. sphere, disk, hoop
C. hoop, sphere, disk
D. hoop, disk, sphere.
The moment of inertia of a hoop is its mass times its radius squared (mr^2). The moment of inertia of a disk is ½ its ...
The solution investigates the rolling of disk, hoop, and sphere down an inclined plane.
