a cyclist and a car are approaching each other at the same speed. the car makes a 500 Hz sound at 343 m/s. the cyclist hears the sound as 535 Hz. How fast are they moving?
f2 = f1(v/v[tex]\pm[/tex]vs)
The Attempt at a Solution
535 hz = 500 hz(343 m/s[tex]\div[/tex]343 m/s-vs)
vs = 22.4 m/s
but the answer should be 11 m/s
