An alert physics student stands beside the tracks as a train rolls slowly past. He notes that the frequency of the train whistle is 478 Hz when the train is approaching him and 451 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.) m/s Need Help? Read It

hw 3 A student knows that an ambulance siren has a frequency of fs = 391 Hz. He measures, when the ambulance is approaching him, the frequency fo = 412 Hz. Assume the speed of sound is 343 m/s in this problem. Input an expression for the ambulance's speed, vs, in terms of the frequencies and the speed of sound v. What is this speed, in meters per second? If ambulance is moving away with the same speed as in part (b), what is the wavelength measured by the student in meters?
