To determine the total horizontal net force applied to the rope, we first need to calculate the total pulling force for each team.
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 can find the net force by subtracting the total pulling force of Team A from the total pulling force of Team B:
Net Force = Total Force of Team B - Total Force of Team A Net Force = 1230 N (left) - 1210 N (right) = 20 N to the left
Therefore, the answer is 20 N to the left.
