I am lost, someone help me solve this problem?
Keep getting the incorrect answer....please help?
After giving an intense performance, a confused and disoriented flautist has wandered onto the motorway!
They are playing a constant 300 Hz tone on their flute and are essentially stationary. If you are driving along the motorway at 100 km/h (27.8 m/s),
What is the frequency you hear from the flautist's instrument before you pass them and after you pass them? (c air = 343 m/s)

F = Fo (V+/-VL) / (V+/-Vs)
VL (V of listener) is + if move toward source and vice versa
Vs (V of source) is + if move away from listener and vice versa
plain old V is speed of sound in the environment
F = 300 (343)/(343-27.8) = 326 Hz
F = 300 (343)/(343+27.8) = 277.5 round appropriately
When you get a good response,
please consider giving a best answer.
This is the only reward we get.
