Two people stand on opposite sides of each other (one on the left and one on the right) pulling on a rope in a game of tug of war. The two people pull on the rope with equal and opposite forces. Which of the following is the expected out come for the work done to the system? No work is done on the rope since the rope has no displacement. Each player does equal amount of non-zero work. The rope moves to the right and the work is positive. The rope moves to the left and the work is negative.
