Homework Help: 3D kinematics problem

  1. Sep 8, 2013 #1
    1. The problem statement, all variables and given/known data
    I know pictures aren't the best, but here it is.

    2. Relevant equations

    3. The attempt at a solution
    This is my work for this problem. Disregard the drawing as it isn't right.

    I'm not sure if I'm misinterpreting the horizontal range part or what. I feel pretty confident about my work but webassign says it's wrong and I don't really see why.
    Link to original if it's not big enough

    The horizontal range of the plane means its distance from the radar site without including the plane's altitude.
    You are treating the horizontal range as the distance to the east, which is incorrect.

    Ahhh. You were absolutely spot on. I was unaware that they were using horizontal in the sense of x and y. Thank you very much.
