Question
Suppose a man is sitting on a chair and exerting 100 N of force downward, while a spring beneath the chair exerts 150 N of force upward. If you assign a negative value to the downward force, what is the net force of this system?(1 point)

To find the net force of the system, we can assign a negative value to the downward force and a positive value to the upward force.
Given:
- Downward force (man): -100 N
- Upward force (spring): +150 N
Now, we can calculate the net force:
Net force = Upward force + Downward force
Net force = 150 N + (-100 N)
Net force = 150 N - 100 N
Net force = 50 N
So, the net force of this system is **50 N**.
Given:
- Downward force (man): -100 N
- Upward force (spring): +150 N
Now, we can calculate the net force:
Net force = Upward force + Downward force
Net force = 150 N + (-100 N)
Net force = 150 N - 100 N
Net force = 50 N
So, the net force of this system is **50 N**.
