Homework Help: Vectors, Direction, and Net displacement

  1. Feb 26, 2010 #1
    I have been working on the following two problems and I cant seem to get any progress.
    Any help from anyone would be greatly appreciated. I know it seems simple to those who are familiar but I have no background in this type of equations.

    1. A helicopter travels northwest 70.7 miles, then straight east 100 miles, and finally straight south 100 miles. How far and in what direction is it from point of origin?

    2. A ship sails 100 miles northwest then 141.4 miles due south. How far and in what direction is it from its starting location?
