Homework Help: Vectors: Canoe on a River

  1. Sep 11, 2009 #1
    1. The problem statement, all variables and given/known data

    I have to find the magnitude of the velocity of vector Vcanoe/river of a canoe relative to the river.

    The canoe has a velocity of 0.520 m/s southeast relative to the earth. The canoe is on the river that is flowing at 0.460 m/s east relative to the earth.

    The angle made my both vectors is 45 degrees.

    2. The attempt at a solution

    I figured the components of the vector Vriver are <0.460,0> m/s
    Components of the vector Vcanoe are approximately <0.707,0.707> m/s since we are working with a 45 degree angle.
    Are my components correct?

    I need subtract both vectors to get the Vcanoe/river.
    I got <0.247,0.707> m/s. Yes?

    I'm not sure if my components are correct and I'm not sure what to do afterwards.
    Any help would be greatly appreciated!
