Displacement: Magnitude and Direction

  1. 1. The problem statement, all variables and given/known data

    Jim walks 100m due south, 60m due east, and then 20m due north. What is his net
    displacement (both magnitude and direction)?

    2. Relevant equations

    I know how to find the net displacement by the magnitude of the distance...
    using the d = sq. rt ( (x2-x1)^2 + (y2-y1)^2 )

    but i dont know how to express the direction?


    3. The attempt at a solution

    Draw the path on graph paper then draw a line back to the start - the direction is just the angle of this line ( usually given from the horizontal x axis )
    The magnitude is the length of this line.
