Three blocks of 20 kg, 50 kg, and 60 kg mass, respectively, are connected by a massless rope that goes over two fixed smooth pulleys and is attached to two hanging masses at its two ends as Find out the acceleration with which the 50 kg mass moves.

Block A of 150 kg mass is constrained to move along a horizontal guide freely. A light rope connects this block with another one, B, of 60 kg mass, that is hanging vertically as Find out the acceleration with which B falls down.
