Body A weighs 100 N, and body B weighs 35 N. The coefficients of friction between A and the incline are μs = 0.56 and μk = 0.25. Angle θ is 40°. Let the positive direction of an x axis be up the incline.
Find acceleration along x.
The Attempt at a Solution
Force of smaller block is just is weight, since it's just freely hanging.
Force of larger block is lessened because it is on an incline and due to friction. This means it will be pulled up the incline?
35 - u100cos40 = ma
15.85 = ma
6.3096 = a
Is my head on right?
