4. An aluminum block of mass m = 2.00 kg and a copper block of mass m2 = 6.00 kg are connected by a light string over a frictionless pulley. They sit on a steel surface as shown in the Figure, where 0 = 30.0°. (a) When they are released from rest, will they start to move? If they do, determine (b) their acceleration and (c) the tension in the string. If they do not move, determine (d) the sum of the magnitudes of the forces of friction acting on the blocks. [Coefficients of friction: 4,1 = 0.610 (aluminum on steel) and µ, 2= 0.530 (copper on steel)] Aluminum Copper m2 Steel
