A 15.0 kg load of bricks hangs from one end of a rope that passes over a small, frictionless pulley. A 28.0 kg counter weight is attached to the other end of the rope, as shown in the figure. You may model the rope as a massless string. The system is released from rest. A. Draw two freebody diagrams, one for the load of bricks and one for the counter weight. 28.0 kg B. Find the magnitude of the upward acceleration of the load of bricks. C. What is the tension in the rope? 15.0 kg
