Two forces are applied to to 17kg as shown in the image. The box is on a smooth surface. Which statement describes the acceleration of the box.

• The box accelerations at 1 m/s² to the right because the net force is 17N to the right.

• The box acceleration at 1.9 m/s² to the right because the greater force is to the right.

• The box accelerations at 3 m/s² because the combined forces cause the box to accelerate.

• The box does not accelerate
