A block of mass m1 = 36 kg on a horizontal surface is connected to a mass m2 = 22.3 kg that hangs vertically as shown in the figure below. The two blocks are connected by a string of negligible mass passing over a frictionless pulley. The coefficient of kinetic
friction between m1 and the horizontal surface is 0.27. (a) What is the magnitude of the acceleration of the hanging mass? m/s2 (b) Determine the magnitude of the tension in the cord above the hanging mass.
