1. Two masses, A and B, lie on a frictionless table. See the figure below. They are attached to either end of a rope with fixed length 11, which passes around a pulley. This pulley can move without friction over the table, and is attached to a second rope with fixed length ly. The second rope passes over a fixed pulley and is attached to a hanging mass C on the other end. Assume that the masses of the ropes and the pulleys are negligible. А. B (a) Draw the force diagrams and give the equations of motions (of the center of masses) of the masses and the pulleys. (b) Determine the tension in the two ropes. (c) Determine the acceleration (magnitude and direction) of the masses.
