Question

A marble block of mass m1 = 500.1 kg and a granite block of mass m2 = 237.4 kg are connected to each other by a rope that runs over a pulley, as shown in the figure. Both blocks are located on inclined planes with angles á = 35.3 degrees and â = 56.7 degrees. Both blocks move without friction, and the rope glides over the pulley without friction. What is the acceleration of the marble block? Note that the positive x-direction is indicated in the figure
