two blocks are connected by a light rope over a pulley fixed at the edge of a table such that bloc A, 16kg is a the table top and block B, 8kg is hanging by the edge.
block A is acted upon by a mass of 200N acting towards the center of table surface. the coefficient of kinetic friction btn block a and horizontal surface is 0.4. if the system is released from rest , determine the velocity of the velocity of the two blocks when block A has moved 3m. use method of work energy principle.
