A box is on a flat surface and is pulled by a cable with a magnitude FT at an angle θ degrees above the horizontal as shown in the figure. If the box is moving with constant speed, what are the relationships between the magnitudes of the normal (FN) and gravitational (Fg) forces, as well as the tension (FT) and the frictional (Ff) forces?
