Two horizontal forces, and , are acting on a box, but only is shown in the drawing. 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 = +5.6 N and the mass of the box is 3.1 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.

Need help with only part b. Got the rest
Fnet= F1 + F2
Fnet=mass * acceleration
+5.6+ F2= (3.1)a
A) F2= (3.1)(+5.8) - 5.6
B) F2= (3.1)(-5.8) - 5.6
C) F2= 0 - 5.6
Fnet=mass * acceleration
+5.6+ F2= (3.1)a
A) F2= (3.1)(+5.8) - 5.6
B) F2= (3.1)(-5.8) - 5.6
C) F2= 0 - 5.6
