Two forces are applied to a 17 kg box, as shown. The box is on a smooth surface. Which statement best describes the acceleration
of the box? A. The box accelerates at 1.0 m/s2 to the right because the net force is 17 N to the right. B. The box accelerates at 1.9 m/s2 to the right because the greater force is to the right. C. The box accelerates at 3.0 m/s2 because the combined forces cause the box to accelerate. D. The box does not accelerate, because neither force is large enough to move the box.
