A hiker starts at his camp and moves the following distances while exploring his surroundings: 70.0m north, 2.75 x 10^2m east, 130m at an angle 30.0 degrees north of east, and 1.50 x 10^2m 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?
b) the order does not matter. It's simple vector addition, which is commutative.
a) The displacements for each section of the trip are:
add them up to get (388,-20)
