To calculate the total horizontal net force applied to the rope, we need to sum the pulling forces for each team and then determine the direction of the net force.
Team A:
- Darlene: 360 N
- Eric: 400 N
- Keshawn: 450 N
Total pulling force from Team A: \[ 360 , \text{N} + 400 , \text{N} + 450 , \text{N} = 1210 , \text{N} \text{ (to the right)} \]
Team B:
- Anita: 350 N
- Frank: 390 N
- Molly: 490 N
Total pulling force from Team B: \[ 350 , \text{N} + 390 , \text{N} + 490 , \text{N} = 1230 , \text{N} \text{ (to the left)} \]
Now, we can determine the net force: \[ \text{Net Force} = (\text{Force of Team A}) - (\text{Force of Team B}) \] \[ \text{Net Force} = 1210 , \text{N} , \text{(to the right)} - 1230 , \text{N} , \text{(to the left)} \] \[ \text{Net Force} = 1210 , \text{N} - 1230 , \text{N} = -20 , \text{N} \]
A negative net force indicates that the net force is to the left. Therefore, the total horizontal net force applied to the rope is:
20 N to the left.
