## Homework Statement

A 5kg hollow metal cylinder with a radius 0.1m rolls off the edge of a roof with an incline of 30degrees and height of 1metre.

If the cylinder was initially at rest, what is the ratio of the rotational to linear kinetic energy when it reaches the end of the roof?

and the ration when it hits the ground?

I don't understand what "The ratio of rotational to linear kinetic energy" means

does it mean the angular velocity? or the velocity?
