You are standing still, just to the side of a set of train trackers. A train passes by, moving at 25.0 m/s just as it passes by, it blows its whistle, and it continues blowing its whistle for a full minute. When the train is directly in front of you the whistle is 5.0 m away and you hear a frequency of 500.0 Hertz at an intensity level of 90.0 dB. After 10 second the train passes it is 250 meter from you and receding.

(A) Find the frequency of the sound you hear from the whistle?

(B) Determine the intensity of the sound from the whistle?

One minute after the train passes it is 1500 meter away and receding.
