Consider three force vectors F1 with magnitude 51 N and direction 150◦ , F2 with magnitude 36 N and direction −41◦ , and F3 with magnitude 11 N and direction 110◦ . All direction angles θ are measured from the positive x axis: counter-clockwise for θ > 0 and clockwise for θ < 0.
a. What is the magnitude of the resultant vector F~ = F1 + F2 + F3?
b. What is the direction of the net force vector F?
