What is the coefficient of static friction for the 200 kg file cabinet when the maximum static frictional force is observed to be 600 N? What is the kinetic frictional force for the same file cabinet when the frictional force once it starts sliding drops to 392 N? In a paragraph or two, how would you explain these concepts of friction to someone in elementary school with the premise being that you can push on a chair and it does not move, then you push harder and it still does not move, but when you push a little harder still, it starts sliding across the floor
