A police car coming toward you from the east (as you move westward) has a siren on at an unknow frequency. As he approaches you hear a frequency of 510 hertz but as he passes you and continues away you hear the pitch drop to 400 HZ. You are traveling at a constant 15 m/sec speed throughout. How fast is the police car traveling? 26.7 m/s 31.4 m/s 18.6 m/s 21.5 m/s In the previous problem, what was the actual frequency of the siren? 436 HZ 451 HZ 482 HZ 500 HZ

Step 1
In this problem, we are asked to determine how fast the police car is traveling. To do this, we need to find the speed of the police car at various frequencies. First, we find the speed at 436 HZ. Show more…

A driver travels northbound on a highway at a speed of 20.0 m/s. A police car, traveling southbound at a speed of 44.0 m/s, approaches with its siren producing sound at a frequency of 2550 Hz. (a) What frequency does the driver observe as the police car approaches? Hz (b) What frequency does the driver detect after the police car passes him? Hz (c) Repeat parts (a) and (b) for the case when the police car is traveling northbound. While the police car overtakes Hz after the police car passes Hz.

A police car is traveling due east at a speed of $15.0 \mathrm{~m} / \mathrm{s}$ relative to the earth. You are in a convertible following behind the police car. Your car is also moving due east at $15.0 \mathrm{~m} / \mathrm{s}$ relative to the earth, so the speed of the police car relative to you is zero. The siren of the police car is emitting sound of frequency $500 \mathrm{~Hz}$. The speed of sound in the still air is $340 \mathrm{~m} / \mathrm{s}$ (a) What is the speed of the sound waves relative to you? (b) What is the wavelength of the sound waves at your location? (c) What frequency do you detect?
You are driving along a highway at 35.0 m/s when you hear the siren of a police car approaching you from behind and you perceive the frequency as 1390 Hz. You are relieved that he is in pursuit of a different speeder when he continues past you, but now you perceive the frequency as 1320 Hz. What is the frequency of the siren in the police car? The speed of sound in air is 343 m/s A) 1350 Hz B) 1370 Hz C) 1360 Hz D) 1300 Hz E) 1320 Hz
