Two horizontal forces, ₁ and ₂, are acting on a box, but only ₁ is shown in the drawing. ₂ 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 ₁ = +19.0 N and the mass of the box is 3.0 kg. Find the magnitude and direction of ₂ when the acceleration of the box is

(a) +5.0 m/s²,

(b) –5.0 m/s², and

(c) 0 m/s²
