Two constant forces of magnitudes F1 and F2, act on a particle of mass 5.00 [kg] which is at rest at the origin. The force F1 points at 14.5° west of north, while the force F2, points at 58.3° west of south. Due to the two forces, the particle accelerates and is later located at 32.4 [m], 17.0° north of west with speed 12.2 [m/s]. What is F1?
