A train is traveling at 30.0 m/s relative to the ground in still air. The frequency of the note emitted by the train whistle is 262 Hz.
The speed of sound in air should be taken as 344 m/s.
Part A
What frequency fapproach is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and approaching it?
Express your answer in hertz.
Part B

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.)

While on a train moving east at a speed of (24.0 + A) m/s relative to the tracks, a passenger walks to the back of train at a speed of 1.60 m/s relative to the train. Relative to the ground, how far east does the passenger travel in (32.0 + B) seconds? Calculate the answer in meters (m) and rounded to three significant figures. A = 7 and B = 19.

While on a train moving east at a speed of 29.0 m/s relative to the tracks, a passenger walks to the back of the train at a speed of 1.60 m/s relative to the train. Relative to the ground, how far east does the passenger travel in 52.0 seconds? Calculate the answer in meters (m) and rounded to three significant figures.
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...
