Component method for vectors

  1. Feb 23, 2014 #1
    1. The problem statement, all variables and given/known data
    Use the componant method to determine the total displacement given by the two vectors shown in each diagram.

    2. Relevant equations



    3. The attempt at a solution

    I thought I just had to find the third unknown side, and use the pythagorean theorem, but I was getting the wrong answer. My book says 11 km.

    Any help is appreciated.

    You've got to add up the x components , add up the y components, then use Pythagoras
