3. Two blocks, mi = 9 kg and m2 = 15 kg, are connected by a light string that passes over a frictionless pulley as shown in the figure. The first block lies on a horizontal surface and is connected to a spring with 45 N/m force constant. The system is released from rest when the spring is at equilibrium (unstretched). If the kinetic friction between mị and the surface is 0.20, calculate: (a) the distance h which the hanging block falls before coming to rest. (b) the work done by the spring on mị (c) the work done by the string on m| k
