To find the total horizontal net force applied to the rope, we need to calculate the total pulling force for each team and then determine the difference between the two.
Team A's total pulling force:
- Darlene: 360 N
- Eric: 400 N
- Keshawn: 450 N
Total for Team A = 360 N + 400 N + 450 N = 1210 N
Team B's total pulling force:
- Anita: 350 N
- Frank: 390 N
- Molly: 490 N
Total for Team B = 350 N + 390 N + 490 N = 1230 N
Now, we find the net force by subtracting Team A's total force from Team B's total force.
Net force = Team B's total force - Team A's total force Net force = 1230 N - 1210 N = 20 N
Since Team B pulls to the left, the net force is to the left.
So, the total horizontal net force applied to the rope is 20 N to the left.
