Find analytically the sum or resultant of the following displacements:
A= 10m Northwest , B= 20m 30 degree north of east and C = 35m due Souh

  1. Henry

    All angles are measured CCW from +x-axis:
    Fr = 10m[135o] + 20m[30o] + 35m[270o].
    Fr = (-7.07+7.07i) + (17.32+10i) + (0-35i),
    Combine like-terms and convert to polar form:
    10.25 - 17.93i = 20.7m[-60o] = 20.7m[60o] S. of E.
