A flat-bottomed object with a mass of 38.6 kg is at rest on a level surface. A variable force is applied to the object, and it is discovered that the object will start sliding if the applied force is greater than 112 N. What is the coefficient of static friction?

Answer :

Final answer:

The coefficient of static friction is a key parameter that determines the maximum force needed to overcome static friction between two surfaces in contact.

Explanation:

The coefficient of static friction is the ratio of the maximum static frictional force that needs to be overcome to the normal force between the surfaces in contact. In this case, the coefficient of static friction can be calculated using the formula:

Coefficient of static friction = Maximum static frictional force / Normal force.

Given that the maximum force before sliding is 112 N and the weight of the object is 38.6 kg, you can calculate the coefficient of static friction as 112 N / (38.6 kg * 9.8 m/s²).
