Two horizontal forces, F and F, are acting on a box, but only F is shown in the drawing. E 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 +9.2 N and the mass of the
box is 3.9 kg. Find the magnitude and direction of when the acceleration of the box is (a) +5.8 m/s2, (b)-5.8 m/s², and (c) 0 m/s².
