How is the fnet in this scenario 0 in both the x and y compo

    1. The problem statement, all variables and given/known data
    A flag of mass 2.5 kg is supported by a single rope as show in figure 13. a strong horizontal wind exerts a force of 12 N on the flag. Calculate the tension in the string?

    2. Relevant equations
    0=Fg-Tsinθ
    0=12-Tcosθ

    3. The attempt at a solution
    I get the right answer when both the fnets = 0, but I don't get understand how in a situation like that that would be the case, isn't the the wind exerting force on the flag so it moves at an angle?

    Yes. You have two forces acting on the flag: aerodynamic drag and gravity.

    Not sure what you are bothered by. Are you questioning the way the flag is shown, i.e. as horizontal?
