You desire to use the horizontal force ?⃑ air from a jet of air created by a fan to hold a 5.0 kg block stationary against a vertical wall by taking advantage of static friction. If the coefficient of static friction between the block and the wall is 0.30, what is the weakest that ?⃑ air can be and still keep the block from falling?

A 12 N horizontal force F pushes a block weighing 5.0 N against a vertical wall (Fig. 6-26). The coefficient of static friction between the wall and the block is 0.60, and the coefficient of kinetic friction is 0.40. Assume that the block is not moving initially, (a) Will the block move? (b) In unit-vector notation, what is the force on the block from the wall?
A horizontal force F of module 12 N is exerted on a block, whose weight is 5 N, to try to hold it against a vertical wall. It is considered that the coefficient of static friction (μs) between the wall and the block is 0.60 while the coefficient of dynamic friction (μc) is 0.40. Initially, the block is rest. Under these conditions, will the block move? Support your answer with a calculation.
