1. The problem statement, all variables and given/known data A horizontal force F of 16 N pushes a block weighing 6.0 N against a vertical wall (Fig. 5-47). The coefficient of static friction between the wall and the block is 0.61 and the coefficient of kinetic friction is 0.41. Assume that the block is not moving initially. (b) In unit-vector notation, what is the force exerted on the block by the wall? ______i + ______j 2. Relevant equations mg static friction formula 3. The attempt at a solution i have no idea what to do. don't really understand this concept and its vectors. Please help.
