- A spectator at a parade receives an 888 Hz tone from an oncoming trumpeter who is playing an 881 Hz note. At what speed v., is the musician approaching if the speed of sound is 337 —? VS' m S 903 m S ! No, that's not the correct answer.Meatloaf (google/youtube him if you’re too young to know the reference) plays an F on his guitar as he races down the highway at 100.0mph on his motorcycle. (The song “Bat out of Hell” is in F major.) An F has a frequency of349.23Hz. First convert 100mph to meters per second. What frequency will a person standing along side the road hear as meatloaf approaches? (Hint, use the Doppler equation we derived in class. The speed of sound in air is 343m/s.)A fire whistle emits a tone of 170 Hz. What is the wavelength of the fire whistle? 0.5 m. 1.0 m. 2.0 m. 3.0 m. Cannot be determined.
- Going down the road at 65 miles per hour on a 86.0 °F summer day, Bari heard a siren approaching. Bari knows that a police siren's frequency is 1280.0 Hz, but it didn't sound like that. Bari pulled over a lane, without slowing down, after seeing the flashing lights of the police car coming up from behind, and the police passed going 25 miles per hour faster than Bari was going. (1 mile = 1.60 km) a) what was the speed of sound on that warm summer day? b) How fast, in m/s, was the police car going? c) What frequency did Bari hear from the siren before the police car passed? d) What frequency did Bari hear from the siren after the police care had passed?A bat is flying 5.10 m/s is chasing an insect flying in the same direction. The bat emits a 39.9 kHz chirp and receives back an echo at 40.6 kHz. What is the speed of the insect ?A truck travelling west at 60 m/s sounds it's 440 hz horn as it passes a stationary observer. What frequency does the observer hear as the car approaches and recedes?
