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
The correct answer is:
A The box accelerates at 1.0 m/s2 to the right because the net force is 17 N to the right.
This is because the net force is the vector sum of the two forces acting on the box. In this case, both forces are acting in the same direction (to the right), so they add up to give a net force of 17 N to the right. According to Newton's second law, F = ma, where F is the net force, m is the mass of the object, and a is the acceleration. Rearranging the formula, we have a = F/m. Plugging in the values, we get a = 17 N / 17 kg = 1.0 m/s2. This means that the box accelerates at 1.0 m/s2 to the right.
