Two trains are traveling toward each other at 30.6 m/s relative to the ground. One train is blowing a whistle at 580 Hz. (Give your answers to at least three significant figures.)
(a) What frequency will be heard on the other train in still air?
(b) What frequency will be heard on the other train if the wind is blowing at 30.6 m/s toward the whistle and away from the listener?
(c) What frequency will be heard if the wind direction is reversed?
