Solve the all parts of given question:

Question: A block of mass m1 = 38 kg on a horizontal surface is connected to a mass m2 = 22.2 kg that hangs vertically. 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. (Assume gravity acts toward the +y direction and the +x-axis is parallel to the surface and to the right.)

Part A: What is the acceleration of the hanging mass? (Indicate the direction with the sign of your answer.)

m/s²

Part B: Determine the tension in the cord. (Indicate the direction with the sign of your answer.)

N
