Chapter 16, Problem 16.47E
Two train whistles, A and B, each have a frequency of 392 Hz. A is stationary and B is moving toward the right (away from A) at a speed of 35.0 m/s. A listener is between the two whistles and is moving toward the right with a speed of 15.0 m/s (Fig. E16.47). No wind is blowing. (a) What is the frequency from A as heard by the listener? (b) What is the frequency from B as heard by the listener? (c) What is the beat frequency detected by the listener?

If a human ear canal can be thought of as resembling an organ pipe, closed at one end, that resonates at a fundamental frequency of 3.0 x 103 Hz, what is the length of the canal? Use a normal body temperature of 37.0°C for your determination of the speed of sound in the canal.
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.
The whistle of a factory is sounding with a frequency of 700 Hz. (a) What frequency will be heard by a worker approaching the factory on her bike at 20 km/h? (b) What frequency will be heard by another work walking away from the factory with 4 km/h? Assume the speed of sound to be 343 m/s.
