[SOLVED] Velocity of ring, disk, and sphere down incline?

In an upcoming physics test, one of the problems is to find the velocity of a ring, disk, and sphere of unknown masses and radii down an incline of unknown length and angle. The specific instruction is to find what coefficient of gh under a radical equals the velocity of each, or V = sqrt(_gh). I know that conservation of energy and moment of inertia are involved, but I'm stuck beyond that. I know the answer to each already and saw how the coefficients might be found when using the equation for rolling kenetic energy, but didn't know how to eliminate the unwanted elements.

Edit: Nevermind, I got it.
