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)

Answer 1

To find the net force in the system, we need to combine the forces acting on the man.

Given:

• Downward force (man sitting): -100 N (assigned negative value)
• Upward force (spring): +150 N

To find the net force, we can add these two forces together:

Net force = (-100 N) + (+150 N) = -100 N + 150 N = 50 N

Therefore, the net force of this system is: 50 N.
