A force F with a magnitude of 10 N is applied to three identical blocks, as shown in the figure. The blocks move from left to right along the same rough horizontal surface. The coefficient of kinetic friction between the blocks and the surface is 0.22. (a) Draw the free body diagram of the blocks. (b) Which case, A, B, or C, has the largest frictional force? Why? (c) Determine the acceleration of the block in the first case (case A) if m = 0.500 kg.
