Two trains approach each other on separate but adjacent tracks. Train 1 is traveling at a speed of 29.9 m/s and train 2 at a speed of 21.6 m/s. If the engineer of train 1 sounds his horn which has a frequency of 520 Hz, determine the frequency of the sound heard by the engineer of train 2. (Use 343 m/s as the speed of sound. Enter your answer to the nearest Hz.)______ Hz

Two trains approach each other on separate but adjacent tracks. Train 1 is traveling at a speed of 35.9 m/s and train 2 at a speed of 27.6 m/s. If the engineer of train 1 sounds his horn which has a frequency of 520 Hz, determine the frequency of the sound heard by the engineer of train 2. (Use 343 m/s as the speed of sound. Enter your answer to the nearest Hz.)

Problem 1. You're walking through the woods and come upon some railroad tracks. You walk southward beside the tracks at 1.00 m/s as you hear a train horn north of you emitting a sound at 650 Hz. Knowing from your previous experience with trains, the sound should be a 500 Hz tone. Take the speed of sound to be 340 m/s. a) How fast is the train moving relative to you? b) Further knowledge of a train whistle says that...
