Homework Help: Three forces on a particle

  1. Dec 13, 2009 #1
    1. The problem statement, all variables and given/known data
    Three forces act on a particle. What is the direction of the resultant of these forces.
    The three forces are: a 65 N force at 30 degrees, a 30N force at 180 degress (going towards the negative x-direction), and a 20 N force at 250 degrees (in the negative x and y directions) the object being at the origin


    2. Relevant equations



    3. The attempt at a solution
    i just want to know if i could just find the resultant of two forces, than take that resultant and the remaining force and take the resultant of that and find the angle

    Vector addition is commutative: (A+B) + C = A + (B+C). So yeah, that should work.
