During a game of pool, a cue ball travels to the left with 70 N of force and collides with the four ball moving with a force of 50 N to the right. If you assign a negative value to the force moving to the right, what is the net force of this system?(1 point)

-20 N
The net force of a system is calculated by adding up all the individual forces acting on the system. In this case, we have a force of 70 N to the left and a force of -50 N (which is equivalent to a force of 50 N to the right but assigned a negative value).
Net force = 70 N + (-50 N) = 20 N
Therefore, the net force of this system is 20 N.
