When at rest, two trains have sirens that emit a frequency of 300Hz. The trains travel toward one another and toward an observerstationed between them. One of the trains movesat 26.0 m/s, and the observerhears a beat frequency of2.6 beatsper second. What is the speed of the second train, which travelsfaster than 26.0 m/s?
