To calculate the total horizontal net force applied to the rope, we need to sum the pulling forces of each team and then find the difference between the two teams.
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, calculate the net force: Since Team A pulls to the right and Team B pulls to the left, we can find the net force as follows:
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)
Thus, the total horizontal net force applied to the rope is 20 N to the left.
