A boy is standing at a railroad crossing for a track that runs east and west. As he faces the track, east is to his right and west is to his left. Two trains on the track some distance apart are headed west, both at speeds of 8.60 m/s, and blowing their whistles (which have the same frequency). One train is approaching him from the east and the other is traveling away from him toward the west. (Assume the speed of sound is 343 m/s.) (a) If he hears a beat frequency of 6.00 Hz, determine the frequency (in Hz) emitted by the two whistles. Hz (b) What If? What would be the frequency (in Hz ) of the beats that he hears if the lead train stops at a station (and continues to blow its whistle) while the second train continues traveling toward him? Hz
