Body A in Fig. 6-33 weighs 100 N, and body B weighs 65 N. The coefficients of friction between A and the incline are µs = 0.51 and µk = 0.26. Angle ? is 34°. Let thepositive direction of an x axis be down the slope. What is the acceleration of A if A is initially (a) at rest, (b) moving up the incline, and (c) moving down theincline?

The figure shows an incline rising toward the right with a body A on the incline attached to a rope connected to a pulley on the edge of the incline. Hanging from thepulley is another body b. The angle theta is between the incline and the horizontal.
