3. We denote GFas the horizontal force of the person exerted on the crate (in the +xdirection),Gfkis the force of kinetic friction (in the –xdirection), NFis the vertical normal force exerted by the floor (in the +ydirection), and mgGis the force of gravity. The magnitude of the force of friction is given by fk= μkFN(Eq. 6-2). Applying Newton’s second law to the
