A car traveling 35.0 m/s overtakes another car going only 22.0 m/s. When the faster car is still behind the slower one, it sounds a horn of frequency 1500.0Hz. What is the frequency heard by the driver of the slower car?

What is the altitude of the plane?

  1. Fo = ((Vs+Vo)/(Vs-Vh)*Fh.
    Fo = ((343+22)/(343-35))*1500 - 1777.6 Hz.

    Fo = Freq. heard by the observer(slower driver).

    Vs = Speed of sound.

    Vo = Speed of the observer(slower driver).

    Vh = Speed of the horn(faster driver).

    Fh = Freq. of the horn.
