7. Two teams are competing in a tug-of-war contest. Team A is pulling at 4000N and Team B is pulling at 4900N is the opposite direction. Sketch the forces and show the net force exerted. Which team is winning Is this force balanced or unbalanced?

Answer:
The Team B is winning. The force is unbalanced.
Explanation:
Step 1: First we must fix a positive sense to the forces exerted. We take as positive the force of 4900 N.
Step 2: Now we must add forces to determine the value of the resulting force ([tex]F_{r}[/tex]).
[tex]F_{r}[/tex] = 4900 N - 4000 N = 900 N
Since [tex]F_{r}[/tex] is positive, team B will win the competition.
The resulting force is unbalanced because if it is balanced it should give 0.
Have a nice day!
