When one train is at rest in the station and the other is

Reference no: EM13638620

Two train whistles have identical frequencies of 160 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 Hz when the whistles operate together. If the speed of sound is 345 m/s, what are the two possible speeds that the moving train can have?

a) moving towards the station

b) moving away from the station

When at rest, two trains have sirens that emit a frequency of 300 Hz. The trains travel toward one another and toward an observer stationed between them. One of the trains moves at 25.5 m/s, and the observer hears a beat frequency of 2.8 beats per second. What is the speed of the second train, which travels faster than 25.5 m/s?
