Chapter 14, Problem 26P

A train is moving past a crossing where cars are waiting for it to pass. While waiting, the driver of the lead car becomes sleepy and rests his head on the steering wheel, unintentionally activating the car’s horn. A passenger in the back of the train hears the horn’s sound at a frequency of 428 Hz and a passenger in the front hears it at 402 Hz. Find (a) the train’s speed and (b) the horn’s frequency, assuming the sound travels along the tracks.

An air controller on an aircraft carrier sees a jet fly over 81 meters above her and she hears the sonic boom when the jet is140 meters past her.  What is the speed of the jet if the speed of sound is 344 m/s?Group of answer choices (81/140)*344 m/s (140/344)*81 m/s (140/81)*344 m/s
You are driving along a highway at 32 m/s when you hear the siren of an emergency vehicle traveling in the opposite direction on the other side of the highway. When the vehicle is approaching you, you hear the frequency of the siren as 2300 Hz, but when it is past you the frequency becomes 1600 Hz. What is the speed of the vehicle? The speed of sound in air is 343 m/s.
An alert physics student stands beside the tracks as a train rolls slowly past. He notes that the frequency of the train whistle is 466 Hz when the train is approaching him and 454 Hz when the train is receding from him. Using these frequencies, he calculates the speed of the train. What value does he find? (Assume the speed of sound in air is 343 m/s.) m/s
