A 10 N horizontal force pushes a block weighing 4.9 N against a vertical wall (Fig. 6-26). The coefficient of static friction between the wall and the block is 0.55, and the coefficient of kinetic friction is 0.35. Assume that the block is not moving initially. In unit-vector notation (Fx i + Fy j), what is the force on the block from the wall?
