Consider two cylindrical objects of the same mass and radius. Object A is a solid cylinder whose moment of inertia I $=1/2$ mr$2,$ whereas object B is a hollow cylinder whose moment of inertia I $=$ mr$2.$ How fast, in meters per seconds, is object A moving at the end of the ramp if it's mass is $195$ kg$,$ it's radius $15$ cm$,$ and the height of the beginning of the ramp is $30\mathrm{.}5$ cm$?$ How fast, in meters per second, is object B moving at the end of the ramp if it rolls down the same ramp?
