Consider two cylindrical objects of the same mass and radius. Object A is a solid cylinder, whereas object B is a hollow cylinder. How fast, in meters per second, is object A moving at the end of the ramp if it's mass is $310$ g$,$ it's radius $39$ cm$,$ and the height of the beginning of the ramp is $41$ cm$?$ How fast, in meters per second, is object B moving at the end of the ramp if it rolls down the same ramp?
