A 15 N horizontal force F→ pushes a block weighing 3.7 N against a vertical wall (see the figure). The coefficient of static friction between the wall and the block is 0.61, and the coefficient of kinetic friction is 0.42. Assume that the block is not moving initially. **(a)** Will the block move? ("yes" or "no") **(b)** In unit-vector notation Fxî+Fyĵ, what is the force on the block from the wall?

Step 1

(a)

The normal force on the on the block is,

Step 2

The force of static friction sis

Step 3

The weight of the block is 3.7N which is less than the stati...
