Question

Suppose you have a tug of war. Both teams are pulling on the rope with 800 pounds of force and both teams and the rope are moving steadily in the direction of one of the teams. What is the relationship between the force team 1 exerts on team 2 and the force that team 2 exerts on team 1.

a. F1 on 2 = F2 on 1
b. F1 on 2 < F2 on 1
c. F1 on 2 > F2 on 1
d. F1 on 2 = -F2 on 1

Answer 1

"Steadily" means constant velocity. That means the net force is 0, so the teams must be pulling with equal force. This means your answer is either A or D.

To figure out which it is, think about the situation. If option A were true, it would mean that the direction of F1 on 2 is the same as the direction of F2 on 1. The force coming from both teams would be aimed in the same direction, so you'd have 1600 N going one way. The net force would not be 0, because everyone would be accelerating in one direction!

This means the answer has to be D, and that makes sense. If one team is pulling with the exact same amount of force as the other team, but in the OPPOSITE direction (as indicated by the "-" sign), the net force would be 0 and neither team would move.

If you need me to clarify anything let me know!

wow thats perfect thanks!
