To determine the total horizontal net force applied to the rope, we need to calculate the total pulling force for each team and then find the difference between them.
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
Net force calculation:
- Team A pulls to the right with 1210 N.
- Team B pulls to the left with 1230 N.
The net force is calculated as: Net Force = Team B's force - Team A's force Net Force = 1230 N (left) - 1210 N (right) = 20 N left
Thus, the total horizontal net force applied to the rope is 20 N to the left.
