Homework Help: Calculating wind speed with respect to an airplane

  1. Mar 26, 2009 #1
    1. The problem statement, all variables and given/known data
    An airplane pilot sets a compass course due west and maintains an airspeed of 220 km/hr. After flying for .5 hr, she finds herself over a town 120 km west and 20 km south of her starting point. Find the wind velocity (magnitude and direction).

    2. Relevant equations

    3. The attempt at a solution
    I have attempted setting up the diagram and finding the vector components of each velocity, and then using right triangles to find the magnitudes, but I keep getting the wrong answer. I have no idea how to go about doing this problem.

    Can you show us how you set up your vector equations?
