Question

A stationary police car emits a sound of frequency 1225 Hz that bounces off of a car on the highway and returns with a frequency of 1265 Hz. The police car is right next to the highway, so the moving car is traveling directly toward or away from it.

What frequency would the police car have received if it had been traveling toward the other car at 22.0 m/s?

P/s: the car was moving 5.53 m/s

Answer #1

stationary police car emits a sound of frequency 1200 Hz that
bounces off of a car on the highway and returns with a frequency of
1280 Hz . The police car is right next to the highway, so the
moving car is traveling directly toward or away from it.
Part A: How fast was the moving car going?
Part B: Was the moving car moving towards or away from the
police car?
Part C: What frequency would the police car...

A stationary police car emits a sound of frequency 1200 Hz that
bounces off of a car on the highway and returns with a frequency of
1230 Hz . The police car is right next to the highway, so the
moving car is traveling directly toward or away from it. Part A How
fast was the moving car going?
What frequency would the police car have received if it had been
traveling toward the other car at 17.0 m/sm/s ?...

A siren of a police car at rest emits at a predominant frequency
of 1310 Hz. A frequency of 1390_Hz is heard when the police car is
approaching an observer standing by a bus stop. a) What is the
velocity of the police car in m/s? b) what will be the frequency
heard by the person standing at the bus stop when the police car is
moving away? and c) Report the velocity of the police car in miles
per...

A moving source emits a sound of frequency 600.0-Hz. A
stationary listener detects a frequency of 640.0-Hz. The ambient
temperature is 33.0°C. Determine
a) the speed of sound at the ambient temperature of 33.0°C.
b) the speed of the moving source for the given source and
detected frequencies.

2. A moving police car plays a sound with constant frequency f0.
The police car moves
from the stationary observer on the right, R, towards the
stationary observer on the
left, L. How does the frequency, fL , observed by the observer
on the left compare to
the frequency, fR , observed on the right?
(a) fL > fR
(b) fL < fR
(c) fL = fR
3. A speaker at rest plays a sound with constant frequency f0

A speeder is pulling directly away and increasing his distance
from a police car that is moving at 25.1 m/s with respect to the
ground. The radar gun in the police car emits an electromagnetic
wave with a frequency of 6.98×109 Hz. The wave reflects from the
speeder's car and returns to the police car, where its frequency is
measured to be 312 Hz less than the emitted frequency. Calculate
the speeder's speed with respect to the ground.

A speeder is pulling directly away and increasing his distance
from a police car that is moving at 29 m/s with respect to the
ground. The radar gun in the police car emits an electromagnetic
wave with a frequency of 7.00 109 Hz. The wave reflects from the
speeder's car and returns to the police car, where its frequency is
measured to be 326 Hz less than the emitted frequency. Find the
speeder's speed with respect to the ground.

A race car is traveling towards you and you hear a sound of
frequency 4072 Hz while the car is traveling towards you. Then the
car shoots by you and as the car is traveling away from you, you
hear a frequency of 2774 Hz. The car is moving at a constant speed
during the whole time you hear these two frequencies, what is the
speed (in m/s) of the car

The siren on an ambulance is emitting a sound whose frequency is
2550 Hz. The speed of sound is 343 m/s. (a) If the ambulance is
stationary and you (the "observer") are sitting in a parked car,
what are the wavelength and the frequency of the sound you hear?
(b) Suppose that the ambulance is moving toward you at a speed of
26.2 m/s. Determine the wavelength and the frequency of the sound
you hear. (c) If the ambulance is...

The security alarm on a parked car goes off and produces a
frequency of 758 Hz. The speed of sound is 343 m/s. As you drive
toward this parked car, pass it, and drive away, you observe the
frequency to change by 68.5 Hz. At what speed are you driving?
