Homework Help: Position vector and magnitude problem

  1. Feb 9, 2009 #1
    1. The problem statement, all variables and given/known data

    A position vector in the first quadrant has an x-component of 6.0m and a magnitude of 10m

    What is the value of its y-component?

    2. Relevant equations


    3. The attempt at a solution

    Well I originally thought I could draw a graph where x=6 and y=...then I realized i was solving for y. I don't know what the magnitude bit means. I thought it meant direction, but I don't see how that applies or would help me solve the problem. A little advice on how to solve this problem would be lovely!

    Treat this as a right angle triangle

    The magnitude would be the hypotenuse in this case
