12. A load of bricks with mass mi = 15.0 kg hangs from one end of a rope that passes over a small, frictionless pulley. A counterweight of mass mz = 27.0 kg is suspended from the other end of the rope, as shown in the figure. The 1. system is released from rest. Answer the following two questions: What is the acceleration of the load of bricks? What is the tension in the rope while the load is moving? Draw a labeled free-body diagrams for each mass (label with symbols/letters, not numbers). b. Write out the symbolic equations representing Fnet = ma for each mass (no numbers should be included here). C. Solve for the numerical answers. a. m , 8 b.
