A block of massm₁=36kg on a horizontal surface is connected to a massm₂=22.1kg 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 betweenm₁and the horizontal surface is0.24.(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.
