A load of bricks with mass = 15.8 hangs from one end of a rope that passes over a small, frictionless pulley. A counterweight of mass = 28.8 is suspended from the other end of the rope, as shown in the figure. (Figure 1) The system is released from rest.
Part A What is the magnitude of the upward acceleration of the load of bricks?
Part B What is the tension in the rope while the load is moving?
