Two blocks, of masses M and m, are connected by a light string passing over a very small frictionless pulley. Initially, both of the blocks are at rest because of friction between block M and the horizontal surface. Then blockm is pulled sideways until the string makes angle 0 with the vertical and then released. At this point, the length of string between the pulley and the block is L. Block M begins to slide at the very moment block m passes through its original position. (Part a) [5 points] Draw free body diagram for each block. (Part b) [20 points] According to free body diagram in part (a) write down the equations and find the coefficient of static friction us between block M and the horizontal surface. 4-?
