6. Two masses mA = 2.0 kg and m³ = 5.0 kg are on incline and are connected by a string as shown bwlow. The
coefficient of kinetic friction between each mass and its incline is μ = 0.30. If mA moves up, and m³ moves
down, determine their acceleration. You are ignoring the masses of the pulley and the cord. [T5, C4]
