Laws of Motion problem

  1. Sep 22, 2007 #1
    1. The problem statement, all variables and given/known dataOnly two forces act on an object (mass=3.00kg). F1=60.0N 45.0deg above the +x axis, F2=40.0N on the +x axis. Find the magnitude and direction (relative to the x axis) of the acceleration of the object.

    2. Relevant equations

    3. The attempt at a solution
    (60.0N)(sin(45))=Fy, Fy=42.4N
    (60.0N)(cos(45))=Fx, Fx=42.4N
    ay=34.13 m/s^2
    ax=13.3 m/s^2
    a=36.6 m/s^2
    68.7 deg above +x axis

    I can't figure out where I am going wrong.

    I think here.
