Homework Help: Components of a Vector

  1. Jan 25, 2005 #1
    The speed of an object and the direction in which it moves constitute a vector quantity known as the velocity. An ostrich is running at a speed of 17.0m/s in a direction of 68.0 degrees north of west. What is the magnitude of the ostrich's velocity component that is directed at A. due north and B. due west?

    I think I have drawn the right picture for this problem, but I'm lost on how to write the components down.

    Do you know how to use the (circular) trigonometric functions in a rightangle triangle...??
