A train is moving parallel and adjacent to a highway with a constant speed of 32 m/s.
A train is moving parallel and adjacent to a highway with a constant speed of 32 m/s. A car is traveling in the same direction as the train at 64 m/s. The car's horn sounds at 520 Hz and the train's whistle sounds at 320 Hz. When the car is behind the train what frequency does an occupant of the car observe for the train whistle? The speed of sound is 343 m/s. Answer in units of Hz. When the car is in...

A car drives at a speed of 25 m/s along a road parallel to a railroad track. A train traveling at 15 m/s sounds a horn that vibrates at 300 Hz. (a) If the train and car are moving toward each other, what frequency of sound is heard by a person in the car? (b) If the train and car are moving away from each other, what frequency of sound is heard in the car?

A train is moving pass 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 444 Hz and a passenger in the front hears it at 415 Hz. Find the train's speed and the horn's frequency, assuming the sound travels along...

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 440 Hz and a passenger in the front hears it at 415 Hz. Find the train's speed and the horn's frequency, assuming the sound travels along...

A car is parked 20.0 m directly south of a railroad crossing. A train is approaching the crossing from the west, headed directly east at a speed of 55.5 m/s. The train sounds a short blast of its 312-Hz horn when it reaches a point 20.0 m west of the crossing. What frequency does the car's driver hear when the horn blast reaches the car? The speed of sound in air is 343 m/s. (Hint: Assume that only the component...

A car sounding its horn (rated by the manufacturer at 600 Hz) is moving at 15.0 m/s toward the east. A stationary observer is standing due east of the oncoming car. 1) What frequency will he hear assuming that the speed of sound is 343 m/s? (Express your answer to two significant figures.) 2) What if the observer is standing due west of the car as it drives away? (Express your answer to two significant figures.)
