Hi

Some help with this niggling question.  Thanks

Extracted text: a) An electric motor drives a coaxial gearbox through a clutch. The motor armature has a mass of 50kg and a radius of 18cm, while the mass of the gearbox assembly is 500kg with a radius of gyration of 24cm. If the motor armature is revolving at 3000 rpm and the gearbox is rotating at 500rpm in the same direction. Determine the loss in rotational Kinetic Energy when the gearbox is engaged.
