Q. An alert physics student stands beside the tracks as a train rolls slowly past. He notes that the frequency of the train whistle is 443 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 train. What value does he find? m/s (suppose the speed of sound is 345 m/s.)
