Problem 1. You're walking through the woods and come upon some railroad tracks. You walk southward beside the tracks at 1.00 m/s as you hear a train horn north of you emitting a sound at 650 Hz. Knowing from your previous experience with trains, the sound should be a 500 Hz tone. Take the speed of sound to be 340 m/s. a) How fast is the train moving relative to you? b) Further knowledge of a train whistle says that...

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.)

Have you ever listened for an approaching train by kneeling next to a railroad track and putting your ear to the rail? Young's modulus for steel is Y = 2.0 × 1011 N/m2, and the density of steel is ρ = 7860 kg/m3. On a day when the temperature is 20°C, how many times greater is the speed of sound in the rail than in the air?

Doppler Effect You are waiting at a train station when an approaching express train sounds its 400 Hz horn, warning everyone to stand back from the platform as it passes. If you perceive the frequency of the horn to be 425 Hz as the train approaches, how fast must the train be moving towards you? You may assume the speed of sound is 343 m/s.
