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)

Answer 1

To find the net force of the system, we can consider the forces acting on it.

You have:

• A cue ball moving to the left with a force of 70 N (we'll consider this as positive).
• A four ball moving to the right with a force of 50 N (since we assign a negative value to the right direction, we'll consider this as -50 N).

Now, we can calculate the net force:

Net Force = Force of Cue Ball + Force of Four Ball
Net Force = 70 N + (-50 N)
Net Force = 70 N - 50 N
Net Force = 20 N

Therefore, the net force of this system is 20 N.
