3. GO Two horizontal forces, F, and F, are acting on a box, but only F, is shown in the drawing. F, can point either to the right or to the left. The box moves only along the x axis. There is no friction between the box and the surface. Suppose that F, = +9.0 N and the mass of the box is 3.0 kg. Find the magnitude and direction of F, when the acceleration of the box is (a) +5.0 m/s. (b) -5.0 m/s², and (c) 0 m/s?.
