Finding the speed of an approaching object using the doppler effect and sonar

  1. Oct 6, 2012 #1
    1. The problem statement, all variables and given/known data
    I attatched 2 images, the problem, and my work (including the formula needed)


    This "double shift" is what's getting me. Is it going 2% towards the object, and 2% from it?

    Or I'm I suppose to use 2 functions:F'=(f+xf) and F'=(f+yf) where x + y = 0.04?

    2. Relevant equations
    See pic.

    3. The attempt at a solution
    See pic.

    Do as the hint suggests - in two steps.
