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?

An alert physics student stands beside the tracks as a train rolls slowly past. He notes that the frequency of the train whistle is 464 Hz when the train is approaching him and 441 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.)

A train is approaching a signal tower at a
speed of 40 m/s. The train engineer sounds the 1000 Hz whistle and
a switchman in the tower responds by sounding the 1200 Hz siren.

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...
