An train has a brass band playing a song on a flatcar. As the train leaving the station at 30.0 m/s, a person on the platform hears a trumpet play a note at 3000 Hz. What is the true frequency of the trumpet, vsnd = 343 m/s? Moving source away from the observer; true frequency is 2262 Hz Moving source away from the observer; true frequency is 3262 Hz Moving source towards the observer; true frequency is 3262 Hz Moving observer towards the source; true frequency is 2262 Hz

While chasing the person who released all the ping pong balls, an astronaut is screaming at 694Hz while moving towards the miscreant at 5.2 m/s. The prankster is fleeing, but at only 3.1 m/s. The air on the ISS is kept pretty close to standard pressure and temperature, so the speed of sound is 343 m/s. At what frequency does the prankster hear the yell? Do not actually solve the problem numerically or algebraically, just pick the one equation and define the relevant knowns and single unknown.
A fire truck emits a sound with frequency of 775Hz a. What is the frequency detected by stationary observer if the fire truck is moving 45m/s towards observer? b. What frequency will be frequency detected if the ambulance is moving 45m/s away from the observer? (the speed of sound in air at 20°C is 343 m/s)
You are driving down the street with your windows open enjoying the nice day. On this nice 20°C day, the velocity of sound in air is 343 m/s . You see a person sitting on a park bench and hear him whistling just after you drive by. If the person whistles at a frequency of 1450 Hz and you drive away at a speed of 17 m/s, what frequency of sound do you observe?

An airplane traveling at v = 164 m/s emits a sound of frequency 5.90 kHz. At what frequency does a stationary listener hear the sound during each of the following times? (Use 344 m/s as the speed of sound.) (a) as the plane approaches kHz(b) after it passes kHz
In a television program, a young actor singing at a frequency of 1,200 Hz is approaching a lady at 0.25 m/s. What frequency is heard by the lady? What frequency is heard by a cameraman who is following the actor also at 0.25 m/s? Assume that the temperature is 25°C.
A student attaches a f = 3.5 kHz oscillator to one end of a metal rail of length L = 19 m. The student turns on the oscillator and uses a piezoelectric gauge at the other end to measure that the resulting sound wave takes t = 0.0062 s to travel the length of the rail. What is the speed of the wave in the rail, in meters per second?
A pair of speakers separated by a distance d = 0.700 m are driven by the same oscillator at a frequency of 686 Hz. An observer originally positioned at one of the speakers begins to walk along a line perpendicular to the line joining the speakers as in Figure P14.37. (a) How far must the observer walk before reaching a relative maximum in intensity? (b) How far will the observer be from the speaker when the first relative minimum is detected in the intensity?

An elf is moving behind a Orc bard that is singing very loudly and triumphantly. If the Orc is singing at an average frequency of 377 Hz and joyously skipping forward at a speed of 9.3 m/s, how fast would the elf have to be moving and in what direction for the frequency to be heard as 359 Hz? Take the speed of sound to be 340 m/s.
