Consider three force vectors ~ F1, ~ F2, and ~ F3
with magnitude 43 N and direction 53; mag-
nitude 94 N and direction 162; and magni-
tude 59 N and direction 288, respectively. All
direction angles are measured from the posi-
tive x axis: counter-clockwise for  > 0 and
clockwise for  < 0.
What is the magnitude of the resultant vec-
tor k~F k, where ~F = ~ F1 + ~ F2 + ~ F3 ? Draw the
vectors to scale on a graph to determine the
within ± 5.0%
