A uniform solid cylinder of mass 2 kg and radius 0.2 m is released from rest at the top of a semicircular track of radius 0.7 m cut in a block of mass 
kg as shown in Figure. The block is resting on a smooth horizontal surface and the cylinder rolls down without slipping

As no external force is acting on the system (block+ cylinder) in the horizontal direction, the linear momentum of the system remain conserved in the horizontal direction

As the cylinder reaches the bottommost point of the track, its centre of mass covers a horizontal distance of 0.25 m (
) w.r.t block towards the right. Let the block move by 
in backward direction, then
