Q3. (15 points) Two masses are connected by a string which goes over an ideal pulley as shown in the Figure. Block A has a mass of 3.0 kg and the rough plane inclined 37.0° to the horizontal. If the coefficients of friction between block A and the plane are (u.-0.5 and -0.2) The system initially ate rest. If mass B increases gradually by adding small masses on the top. What is the minimum value the mass B needed for mas A to start moving up? B
