Two horizontal forces F, and F, are acting on a box, but only F, points to the right, F, can point either to the right or to the left. The box moves only along the horizontal 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

Two horizontal forces F, and F, are acting on a box, but only F, points to
the right, F, can point either to the right or to the left. The box moves only
along the horizontal 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].
