A block of wood experiences a normal force of 32 N from a rough,flat surface.there is a rope tied to the blobk.the rope is pulled parallel to the surface and the tension in the rope can be increased to 8 N before the block starts to slide. how can i determine the coefficient of static friction. thanks

To determine the coefficient of static friction, you need to use the formula:

Coefficient of Static Friction = Maximum Static Friction Force / Normal Force

In this scenario, the maximum static friction force is the force at which the block starts to slide, which is equal to the tension in the rope (8 N). The normal force acting on the block is given as 32 N.

Substituting these values into the formula, we get:

Coefficient of Static Friction = 8 N / 32 N

Simplifying the expression, the coefficient of static friction is:

Coefficient of Static Friction = 0.25

Therefore, the coefficient of static friction between the block and the rough, flat surface is 0.25.
