A force diagram showing a person pushing a box is shown below.
 


What is the net force?
A.-110 N
B.+110N
C.+170N
D.+240N

To determine the net force acting on the box in the force diagram, we typically need to know the forces acting on the box and their directions.

If the diagram shows a person pushing the box with a certain force, while other forces (like friction or resistance) act in the opposite direction, we can calculate the net force as the sum of all forces, taking their directions into account (positive for forces in one direction, negative for forces in the opposite direction).

Since the possible answers include both negative and positive values, it seems there are opposing forces. Without the diagram, I can't give the exact values, but here's how to proceed:

### Steps:
1. **Identify all forces** acting on the box, including the pushing force and any opposing forces like friction.
2. **Sum the forces**, ensuring you consider the direction (positive for forces in the direction of the push, negative for opposing forces).
3. The result of this sum is the **net force**.

If you upload the diagram or provide the details of the forces, I can give you a precise calculation.

1. What role does friction play in calculating net force?
2. How do you determine the direction of forces in a diagram?
3. What is the significance of a positive vs. negative net force?
4. Can multiple forces acting in the same direction increase the net force?
5. How does acceleration relate to net force in this context?

**Tip:** Always keep track of directions when summing forces, as opposite directions subtract from each other.
