Vectors problem

  1. Oct 8, 2008 #1
    1. The problem statement, all variables and given/known data
    4 people stand at the corners of a square. Fred stands at point (0,0)
    Ted at (1,0) Ed at (1,1) and ned at (0,1). they each pull on a rope connected to the center of the square
    (0.5,0.5). Fred exerts 11N, Ted exerts 11N, Ed 17N and Ned 15N. what is the net force exerted on the center point and what is the angle from the positive x-axis

    2. Relevant equations

    3. The attempt at a solution
    Fx = 17cos60+11cos60-11cos60-15cos60
    Fy = 17sin60-11sin60-11sin60+15sin60
    fnet = (fx^2+fy^2)^.5
    i am not getting the right anwser where am i going wrong

    Hi myoplex11,

    I don't believe the angles involved here are 60 degrees. What would they be?
