To stop the box from moving, we need to apply a force that is equal in magnitude and opposite in direction to the force that is causing the box to move.
In this case, the force that is causing the box to move is unknown, but we have four options for applying a force to stop the box from moving:
1. Adding 6 N of force pulling to the left: This would not stop the box from moving, as it would be in the same direction as the force causing the box to move.
2. Adding 6 N of force pulling to the right: This would not stop the box from moving, as it would be in the same direction as the force causing the box to move.
3. Subtracting 8 N of force pulling to the left: This would not stop the box from moving either, as it would still be in the same direction as the force causing the box to move.
4. Subtracting 8 N of force pulling to the right: This would be the correct answer, as it would be opposite in direction to the force causing the box to move. By subtracting the 8 N force pulling to the right, we would effectively cancel out the force causing the box to move and bring the box to a stop.
To determine which change in force would stop the box from moving, we need to consider the net force acting on the box. The net force is the sum of all the forces acting on the box.
In this case, the box is already moving, so there must be a net force acting on it. Let's simplify the problem by converting the options to a single direction. We'll consider positive forces as forces pulling to the right and negative forces as forces pulling to the left.
Given the options:
1. Adding 6 N of force pulling to the left (+6 N)
2. Adding 6 N of force pulling to the right (-6 N)
3. Subtracting 8 N of force pulling to the left (-8 N)
4. Subtracting 8 N of force pulling to the right (+8 N)
To stop the box from moving, we need the net force to be zero. This means the forces pulling to the right must be equal to the forces pulling to the left.
From the options, we can see that subtracting 8 N of force pulling to the right (+8 N) would balance out the existing forces and result in a net force of zero. Therefore, subtracting 8 N of force pulling to the right would stop the box from moving.
