Cars, Ropes, Forces and Bisecting Angles

  1. Sep 17, 2008 #1

    1. The problem statement, all variables and given/known data
    A car is being pulled out of the mud by two forces that are applied by the two ropes shown in the drawing. The dashed line in the drawing bisects the = 34.0° angle. The magnitude of the force applied by each rope is 3500 newtons.

    (I attached the image...)

    How much force would a single rope need to apply to accomplish the same effect as the two forces added together?

    2. Relevant equations
    F= ma

    3. The attempt at a solution

    I've tried to use trigonometry, although I don't believe that is the right approach. I can't figure out how any of the motion equations play into this, or how to use the F= ma approach. For some reason I don't even know how to begin the problem. I've tried some of the approaches I just listed, but all give me odd answers. Does anyone have any suggestions??

    Thank you so much in advance.

    this problem is basically asking for the net force of the two forces

    Sorry, I managed to get help from another person before, but forgot to label is 'SOLVED'. (I know the Solved action itself is not working, but I've decided to label them anyway.)

    But thank you! I realize what I was doing wrong.
