Determine what percent of the initial kinetic energy is lost

Reference no: EM13659520

A record is dropped vertically onto a freely rotating (undriven) turn table. Frictional forces act to bring the record and turn table to a common angular speed. If the rotational inertia of the record is .54 times that of the turntable, what percent of the initial kinetic energy is lost?
