Body A in the figure weighs 122 N, and body B weighs 33.5 N. The coefficients of friction between A and the incline are ?s = 0.563 and ?k = 0.243. Angle ? = 40.9°. Let the positive direction of an x axis be up the incline.

What is the acceleration of A if A is initially at rest?

And what is the acceleration of A if A is initially moving up the incline?

And what is the acceleration of A if A is initially moving down the incline?
