Body A in Fig. 6-33 weighs 102 N, and body B weighs 32 N. The coefficients of friction
Chapter 6, Problem 27(choose chapter or problem)
Body A in Fig. 6-33 weighs 102 N, and body B weighs 32 N. The coefficients of friction between A and the incline are ms 0.56 and mk 0.25. Angle u is 40. Let the positive direction of an x axis be up the incline. In unit-vector notation, what is the acceleration of A if A is initially (a) at rest, (b) moving up the incline, and (c) moving down the incline? Frictionless,massless pulleyABFigure 6-33 27 and 28.
