Two blocks are connected by a string that goes over an ideal pulley and pulls on block A parallel to the surface of the plane. Block A has a mass of 3.00 kg and can slide along a rough plane inclined at 30 degrees to the horizontal. The coefficient of static friction between block A and the plane is 0.400. What mass should block B have in order to start block A slidig up the plane?
