You have three equal mass objects, that you release from rest at the top of an incline. Mass A is a disk, Mass B is a solid sphere, and Mass C is a hoop. Which object reaches the bottom of the incline last?
Mass A - Disk
Mass B - Solid Sphere
Mass C - Hoop
All 3 masses arrive at the bottom of the incline at the same time.
It depends on the radius of the objects.
