A train moving at a constant speed is passing a stationary observer on a platform. a flute player is playing a note with frequency of 940Hz. after the flute has passed, the observer hears the sound frequency of 915Hz. What is the speed of the train? The speed of sound in air is 343m/s.
so
Vs = ((Fs/Fo)-1) * v
is that the correct equation
Vs = ((940/915)-1)*343
Vs = 9.37m/s?
