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) Responses 50 kg 50 kg 250 N 250 N -50 N -50 N 50 N

Answer 1

To calculate the net force of the system, you can use the following approach:

1. Assign the downward force (100 N) a negative value, so it is -100 N.
2. The upward force from the spring is positive, so it is +150 N.

Now, find the net force by adding these two forces together:

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

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