A hiker starts at his camp and moves the following distances while exploring his surroundings: 60.0 m north, 2.95 102 m east, 130 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.)
(b) Would changes in the order in which the hiker makes the given displacements alter his final position?
