Yоu аre stаnding оn the plаtfоrm at a train terminal when a high-speed train comes through the station without stopping. The train is sounding its horn intermittently as it approaches, passes and leaves the station. You hear a main frequency of 597 Hz as the train is approaching the station and 349 Hz as it moves away from the station. Assume the air temperature is 15.0 ˚C. a) how fast is the train traveling? b) what is the actual frequency of the horn? (Hint: With the data provided, you can write down two equations in two variables (vS and f) and then solve them to get the frequency and velocity.)
