    two blocks are positioned on surfaces, each inclined at the same angle of 49.4 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 4.61 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.470. Assume static friction has been overcome and that everything can slide....
