A 2.20 kg block is initially at rest on a horizontal surface. A horizontal force of magnitude 4.22 N and a vertical force ℗ are then applied to the block (see the figure). The coefficients of friction for the block and surface are μ = 0.4 and µ = 0.25. Determine the magnitude of the frictional force acting on the block if the magnitude of P is (a)10.0 N and (b)12.0 N. (The upward pull is insufficient to move the block vertically.)
