Question

A block of mass M with the semicircular track of radius R rests on a horizontal smooth surface. A cylinder of radius r slips on the track. If the cylinder is released from rest from the top, the distance moved by block when the cylinder reaches the bottom of the track is, R - r, m R - r M + m, M M + m R - r, M M - m r
