Two masses mA = 1.2 kg and mB = 5.6 kg are on inclines and are connected together by a string as shown in (Figure 1) . The coefficient of kinetic friction between each mass and its incline is μk = 0.30.
If mA moves up, and mB moves down, determine their acceleration. Ignore masses of the (frictionless) pulley and the cord.
Express your answer to two significant figures and include the appropriate units. Enter positive value if the direction of the acceleration is in the direction of the velocity and negative value if the direction of the acceleration is in the direction opposite to the velocity.
