Homework Help: Vector help

  1. Oct 20, 2004 #1
    Three forces act simultaneously on point J. One force is 20.0 N north; the second is 20.0 N west; the third is 20.0 N 60° east of north. Determine the magnitude and direction of the resultant force.
    I need help with this problem. I know you can figure this out by putting it on a graph and adding the cordinates but I cant find the cordinates of the 60º one. The north one is (20,0) and the west is (-20,0).

    Are you familiar with vector components?

    x = 20cos60
    y = 20sin60

    (x,y) for the third force.
