Asked by Jamie
Not at all sure where to start with this problem. Any help would be appreciated!
The siren of an ambulance has a frequency f=500 Hz. A pedestrian standing on a
sidewalk listens to this siren as the ambulance passes by at a speed of 65 mph. The speed
of sound in air is 330 m/s.
Calculate the total shift in frequency detected by the pedestrian as the ambulance
passes.

As the ambulance approaches, the pedestrian will hear a higher frequency. As it recedes a lower frequency. Add the absolute values of the changes.
For the formula, Google Doppler shift (classical not relativistic)
