A hiker starts at his camp and moves the following distances while exploring his surroundings: 69.0 m north, 2.10 ✕ 102 m east, 1.00 ✕ 102 m at an angle 30.0° north of east, and 1.50 ✕ 102 m south.(a) Find his resultant displacement from camp. (Take east as the positive x-direction and north as the positive y-direction.)magnitude mdirection ° south of east(b) Would changes in the order in which the hiker makes the given displacements alter his final position?Yes No
