Two teams are playing tug of war. The tables show the members of each team and how much pulling force each team member applies to the rope.

Answer 1

To find the total horizontal net force applied to the rope, we need to calculate the total pulling force for each team and then determine the net force.

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

Calculating the net force: Team A pulls to the right (+) with a total force of 1210 N, and Team B pulls to the left (-) with a total force of 1230 N.

Net force = Force by Team A - Force by Team B Net force = 1210 N - 1230 N = -20 N

The negative sign indicates that the net force is in the direction of Team B's pull.

Therefore, the total horizontal net force applied to the rope is 20 N to the left.
