Asked by Stephy

An aircraft carrier has a speed of 13.0m/s relative to the water. A jet is catapulted from the deck and has a speed of 67.0m/s relative to the water. The engines produce a 1550-Hz whine, and the speed of sound is 343m/s. What is the frequency of the sound heard by the crew on the ship?


CAN ANYONE PLEASE GIVE ME SOME IDEAS TO DO IT?THANKS A LOT!!!

The observer is moving toward the source at 13m/s, and the source is moving away from the observer at 54m/s. Use the formula.
