To calculate the total horizontal net force applied to the rope, we need to find the total pulling force for each team and then determine the difference between the two.
Total pulling force for Team A:
- Darlene: 360 N
- Eric: 400 N
- Keshawn: 450 N
Total for Team A = 360 N + 400 N + 450 N = 1210 N
Total pulling force for Team B:
- 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 (1210 N) and Team B pulls to the left (1230 N). Net force = Total force of Team B - Total force of Team A Net force = 1230 N - 1210 N = 20 N
Since Team B has a greater pulling force, the net force is directed towards the left.
Thus, the total horizontal net force applied to the rope is 20 N to the left.
