What is the speed of the second train

Reference no: EM13312149

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 33.5 m/s, and the observer hears a beat frequency of 3.2 beats per second. What is the speed of the second train, which travels faster than 33.5 m/s?
