Homework Help: Two Forces on Single Point

  1. Feb 4, 2008 #1
    1. The problem statement, all variables and given/known data
    Two forces, F1 and F2, act at a point. The magnitude of F1 is 9.80 , and its direction is an angle 65.0 above the x-axis in the second quadrant. The magnitude of F2 is 5.00 , and its direction is an angle 52.3 below the x-axis in the third quadrant.

    What is the x-component of the resultant force?

    What is the y-component of the resultant force?

    What is the magnitude of the resultant force?

    2. Relevant equations
    Fcos([tex]\vartheta[/tex]) for X-component

    Fsin([tex]\vartheta[/tex]) for y-component


    3. The attempt at a solution

    I take
    9.8*Cos(180-65) for X-component but thats wrong

    what else should I try.
    Thanks alot.

    Theres 2 forces, why did you only calculate the x-component of the one force. It wants the sum of the x components of both forces.

    This is just what I started on. If I don't get this part right then I won't be able to get the rest right.
