Two train whistles have identical frequencies of 1.77x10^2 Hz. When one train is at rest in the station and the other is moving nearby, a commuter standing on the station platform hears beats with a frequency of 6.00 beats/s when the whistles operate together. What are the two possible speeds that the moving train can have? (a) moving away from the station m/s (b) moving towards the station m/s
