A marble block of mass m1 = 552.0 kg and a granite block of mass m2 = 127.5 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 ? = 35.9? and ? = 55.9?. The rope glides over the pulley without friction, but the coefficient of friction between block 1 and the inclined plane is ?1 = 0.13, and that between block 2 and the inclined plane is ?2 = 0.31. (For simplicity, assume that the coefficients of static and kinetic friction are the same in each case.) What is the acceleration of the marble block? Note that the positive x-direction is indicated in figure.
