An 11N force acting due north and a 22-N force acting 30° North of east act concurrently on a point. What is the equilibrant force at that point? I'm having such a hard time.=(

  1. find resultant and do the opposite.

    11 + 22 sin 30

    22 cos 30

    magnitude = sqrt(north^2 + east^2)

    tan angle north of east
    = north/east

    you want that magnitude
    but opposite direction, same angle south of west
