The coefficient of kinetic friction is
Explanation:
The mass of the object is
The initial speed of the object is
The final speed of the object is
The distance is
Apply the equation of motion
to calculate the acceleration
The acceleration is
According to Newton's Second Law
The frictional force is
The acceleration due to gravity is
The normal force is
The coefficient of kinetic friction is
