What fraction of kinetic energy was lost

Reference no: EM13306804

A uniform disk of mass 4m is rotating an a plane parallel to the ground with angular frequency of 12 rad/sec. A particle of mass, m is dropped on the surface of the disk at a distance r/2 from the center. Assuming the particle sticks to the disk, what is the angular frequency of the disk/particle system after it sticks? What fraction of kinetic energy was lost?
