A uniform hoop and a disk, having the same mass and the same radius, are released simultaneously from rest at
the top of a ramp. Which object reaches the bottom of the ramp first? The ramp is 1.0meter high. The incline of the plane is 30 degrees. Assume no friction. Show mathematically.

drwls,
The disc reaches the bottom first, no matter what the ramp height and angle is. Acceleration depends upon the ratio of moment of inertia to M*R^2.

I understand that but I still have to show it mathematically.
