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?(1point)250 N 50 N 50kg 50 N

Answer 1

To find the net force acting on the system, we can assign a negative value to the downward force and a positive value to the upward force.

• The downward force (the man's weight exerted on the chair) is \( -100 , \text{N} \).
• The upward force (the spring force) is \( +150 , \text{N} \).

Now, we can calculate the net force:

\[ \text{Net Force} = \text{Upward Force} + \text{Downward Force} = 150 , \text{N} + (-100 , \text{N}) = 150 , \text{N} - 100 , \text{N} = 50 , \text{N} \]

Thus, the net force of this system is 50 N.
