Question

All of the following questions are related to the situation above. As such you may work them as a group, i.e. you may not need to draw separate diagrams and expressions for each question. What is the magnitude and direction of the normal force acting on the block? How does the normal force compare to the weight of the block? (if you have them equal you may want to rework the problem!) What is the magnitude and direction of the friction force acting on the block? If the block is just about to slide (i.e. the friction force is maxed out) what is the coefficient of static friction between the block and the floor?

Explanation / Answer

1) The normal force is equal to weight of the block

b) N=1*9.8=9.8 N and is along the y axis

3) The frictional force is mu_N and is directed along the negative xaxis

4) mu_s=f/N
