Concept #1: Intro to Motion in 2D

Concept #2: Position and Displacement in 2D

Practice: At point A, a hiker is 10m east from the origin. After 35s, the hiker arrives at point B 40m at 60° north of east from the origin. Calculate the magnitude and direction of the hiker’s displacement.

Example #1: Your initial position is 6.2 m from the origin, 25° below the x-axis. You then travel 9.9 m at an angle 78° above the positive x-axis, then 2.0 m in the negative x-direction. What is the magnitude & direction of your final position vector?
