Homework Help: What is the magnitude and direction of vector c

  1. Feb 13, 2008 #1
    1. The problem statement, all variables and given/known data

    Vector A points to the right with magnitude 10 m/s, and vector B points upward vertically
    with magnitute of 15 m/s. What is the magnitude and direction of vector c such that A+B+C=0

    Any ideas on this problem are appreciated..

    2. Relevant equations



    3. The attempt at a solution

    A+B+C=0

    (A+B)+C=0

    Find A+B and then to make it zero C would be in the opposite direction of that resultant

    I can do that, but I'm confused about one thing.
    When they that the vector is pointing to the right, does it mean that its direction is 0 degrees from the positive x-axis or its direction is some angle between the the x-axis and the y-axis?

    Well I assuming that it is in the direction of the positive x-axis, else they would have specified the angle(not zero) to which it acts.
