What is the frequency heard by the engineer on train

Reference no: EM13671740

Two trains on separate tracks move toward one another. Train 1 has a speed of 100 km/h, train 2 a speed of 60.0 km/h. Train 2 blows its horn, emitting a frequency of 500 Hz. What is the frequency heard by the engineer on train 1? (Suppose the speed of sound is 345 m/s.)
