3) The two blocks shown in figure, are in contact with rough surfaces with, = 0.25 and 14-0.2. (a) Derive a relationship between the acceleration a of block A and the acceleration a of block B (7 pts) (b) Assuming that block B moves downward, draw the FBDs of blocks A and B (8 pts) (c) Write down the dynamic equilibrium equations for blocks A and B. (12 pts) (d) Solve the system of equations in (alce) for the tension in the cable and acceleration of block B. Based on your answer, how can you say if your assumption that block B moves downwards is correct/wrong?
