A 12 N horizontal force `vecF` pushes a block weighing 5.0 N against a vertical wall (Fig. 6-41). The coefficient of static friction between the wall and the block is 0.00, 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?

Text Solution

Verified by Experts

The block does not slide, (b) `vecF_(w)=-F_(N)hati+fhati=-(12N) hati+(5.0N)hatj`
