The coefficient of kinetic friction between the crate and the floor.
Answer to Problem 69A
The coefficient of kinetic friction between the wooden crate and the floor is
Explanation of Solution
Given:
The mass
The horizontal force
Consider the acceleration due to gravity
Formula used:
Consider a horizontal force acts on the object and the object slides over the surface, frictional force acts between the object and surface. The expression for the kinetic frictional force between the object and the surface as follows:
Here,
Calculation:
The weight
The normal force
So, the value of the coefficient of kinetic friction
Conclusion:
Therefore, the coefficient of kinetic friction between the wooden crate and the floor is
