Ground in direction opposite to first train-receding from it

Reference no: EM13550487

A train is traveling at 30.0m/s relative to the ground in still air. The frequency of the note emitted by the train whistle is 262Hz . The speed of sound in air should be taken as 344m/s . What frequency f approach is heard by a passenger on a train moving at a speed of 18.0m/s relative to the ground in a direction opposite to the first train and approaching it? What frequency f recede is heard by a passenger on a train moving at a speed of 18.0m/s relative to the ground in a direction opposite to the first train and receding from it?
