A block of mass m₁ = 36 kg on a horizontal surface is connected to a mass m₂ = 15.2 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 m, and the horizontal surface is 0.24. m₁ m₂ (a) What is the magnitude of the acceleration (in m/s²) of the hanging mass? m/s² (b) Determine the magnitude of the tension (in N) in the cord above the hanging mass.
