Body A in the figure weighs 92 N, and body B weighs 71 N. Thecoefficients of friction between A and the incline are μs = 0.51and μk = 0.22. Angle θ is 39°. Let the positive direction of an xaxis be up the incline. What is the acceleration of A if A isinitially (a) at rest, (b) moving up the incline, and (c) movingdown the incline?
