Two blocks, with masses 4.00 kg and 8.00 kg, are connected by a string and slide down a 30.0oinclined plane (Figure 1). The coefficient of kinetic friction between the 4.00 kg block and the plane is 0.250; that between the 8.00 kg block and the plane is 0.350. (A) What happens if the positions of the blocks are reversed, so that the 4.00 kg block is uphill from the 8.00 kg block? Calculate the acceleration of the smaller block in this case. (Express your answer with the appropriate units.) (B) Calculate the acceleration of the larger block in this case. (Express your answer with the appropriate units.)
