Three blocks are attached to each other with ropes that pass over pulleys as shown in Figure. The masses of the ropes and pulleys can be ignored, and there is no friction on the surface over which the blocks slide or in the pulleys. Find the acceleration of the blocks. Mass of the block A = 4 kg Mass of the block B = 2 kg Mass of the block C = 6 kg Angle θ = 39 degrees Acceleration due to gravity g = 9.8 m/s^2
