Answer:
The coefficent of static friction is 0.20.
Step-by-step explanation:
The general formula for the coefficient of static friction is = the static frictional force/the normal force. Any measurement of force is in the SI unit of Newtons (N). In this problem, we know that the normal force of the object is 25 N and that it requires a frictional force of 5 N to begin moving over a horizontal surface. When we divide the frictional force of 5 by the normal force of 25, we get an overall coefficent of static friction of 0.20.
