Homework Help: Three forces acting on object, find net force

  1. Apr 11, 2005 #1


    Three forces F1, F2 and F3 act on an object as shown in the free-body diagram above. F1 has a magnitude of 6 N while F2 and F3 each have a magnitude of 3 N. All forces make angles of 30° with the x-axis as shown.

    What is the magnitude of Fnet, the net force acting on the object?

    |Fnet| = N

    I know, this problem isn't too hard, we need to add vectors considering the angles ( both in x -y directions )

    I just forgot how to do this, can any body help.
