Two masses are connected by a string

Reference no: EM13544206

Two masses are connected by a string which goes over an ideal pulley. Block A has a mass of 4.75kg and can slide along the smooth plane inclined by 37.0 degrees above the horizontal. The masses remain stationary. a) draw a free body diagram b) what mass does block B need to have in order for the masses to remain stationary?
