When at rest, two trains have sirens that emit a frequency of 300 Hertz. The trains travel toward one another and toward an observer stationed between them. One of the train's moves at 29.5 meter per second, and the observer hears a beat frequency of 2.7 beats per second. Compute what is the speed of the second train, which travels faster than 29.5 m/s?
