How do you the find magnitude and x component of a vector?

  1. Sep 5, 2009 #1
    1. The problem statement, all variables and given/known data

    The vector -5.2 A has a magnitude of 47 m and points in the positive x direction

    What is the x component of vector A?
    What is the magnitude of vector A?

    2. Relevant equations



    3. The attempt at a solution

    You seem to have missed two important sections:

    2. Vector A = Ax + Ay
    Ax = magnitude X xi
    Ay = magnitude X yi

    3. I dont know how to start.

    Try starting by figuring out how long A is, and in what direction it points.

    Welcome to PF!

    Hi egadda2! Welcome to PF! :smile:

    (try using the X2 tag just above the Reply box :wink:)
    That's very confused :redface:

    you mean A = Ax x i + Ay x j.

    ok, so in this case Ax = … ? :smile:
