A hiker starts at his camp and moves the following distances while exploring his surroundings: 74. 0 m north, 2. 00 ✕ 102 m east, 1. 30 ✕ 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 m direction ° south of east (b) Would changes in the order in which the hiker makes the given displacements alter his final position
