A 5kg block is placed on a rough plane inclined at 25∘ to the horizontal. The coefficients of friction are μs=0.25 and μk=0.20. A force of 40N is applied parallel to the plane, acting upward along the slope. Determine (i) whether the block moves and, if it does, (ii) the magnitude and direction of its acceleration. Take g=9.8ms−2.
