Block A (40 kg) rests on the 30° rough incline in the figure and is connected by a light inextensible rope, parallel to the incline, over a smooth pulley to the hanging block B (30 kg). The coefficients of friction between A and the plane are given in the figure. The system is released from rest. (a) Show whether the system moves, and if so determine the acceleration of the blocks (answer in m/s²); (b) determine the tension in the rope (answer in N). Take g = 9.81 m/s².
