For the problem here, I am given the kinetic friction of the blocks, and I am suppose to find the acceleration of the blocks. I set the x-axis along the incline with x-positive directed towards the right, and I set both the resultant forces of of A and B down the incline since I don't which one goes up or down. Now since A and B will move in opposite directions, how do I know which way to set the frictions?
Here is a diagram of the problem, and a solution I found online,
They also set the resultant forces in the same direction but they set the frictions in different directions.
