In the figure, a force P→ acts on a block weighing 47.0 N. The block is initially at rest on a plane inclined at angle θ = 17.0° to the horizontal. The positive direction of the x axis is up the plane. The coefficients of friction between block and plane are μs = 0.520 and μk = 0.350. In unit-vector notation, what is the frictional force on the block from the plane when P→ is (a) (-5.40 N) î , (b) (-8.20 N) î , and (c) (-15.1 N) î ?.
