Two blocks with masses 4.00 kg and 8.00 kg are connected by a string and slide down a inclined plane (Fig. 5.72). The coefficient of kinetic friction between the 4.00 kg block and the plane is 0.25; that between the 8.00 kg block and the plane is 0.35. (a) Calculate the acceleration of each block. (b) Calculate the tension in the string. (c) What happens if the positions of the blocks are reversed, so the 4.00 kg block is above the 8.00 kg block?
