Cylinder about side, finding angular velocity...
A 5.0 kg, 60-cm-diameter disk rotates on an axle passing through one edge. The axle is parallel to the floor. The cylinder is held with the center of mass at the same height as the axle, then released.

What is the cylinder's angular velocity when it is directly below the axle?
Law of conservation of energy (kinetic and potential of both sides)
I tried to do this problem using mgy=1/2mv^2 but it didnt work...
I know it has something to do with moment of inertia, but do I just add the moment of inertia to the 1/2mv^2 and solve for v?
