Homework Help: Finding distance from sonic boom

  1. Oct 19, 2011 #1
    1. The problem statement, all variables and given/known data

    A supersonic plane passes directly over an observer at point P, flying due west at an altitude of 11.6 km and a speed of Mach 1.60. What is the plane's horizontal distance from point P when the sonic boom is heard?

    I can assume T = 20C therefore Vs = 343 m/s

    2. Relevant equations

    Mach = V/Vs

    Sinθ = V/Vs

    3. The attempt at a solution

    I have no idea. I do know however a right triangle is involved, but I don't know where to go from there.

    Why don't you draw a diagram of the problem and see if that helps?

    Yep. SK's right. It should make the problem clearer.
