A force of 12 N acts on an object of mass 10kg and moves it with a constant velocity across a floor. What is the coefficient of fiction between the object and the floor?

• PHYSICS -

Since the object is not accelerating, the net force is zero and the friction force is 12N (backwards).

The (kinetic) friction force is therefore

mu = 12N/(M*g) = 12/98 = 0.1224
