Two blocks, with masses 4.00 kg and 8.00 kg, are connected by a string and slide down a 30.0 inclined plane . 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. Calculate (a) the acceleration of each block and (b) the tension in the string. (c) 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?

Question

Two blocks, with masses 4.00 kg and 8.00 kg, are connected
by a string and slide down a 30.0 inclined plane . 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. Calculate (a)
the acceleration of each block and (b) the tension in the string. (c) 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?
