Contrived Physics Question

Thanks to Gavin and Roland at Busted Carbon for sending this one to me.



26. A train is blowing it's whistle while traveling at a speed of 22.0 m/s. The speed of sound is 343 m/s. Observer A is directly in front of the train, while observer B is directly behind it. Find the whistle frequency heard by A and that heard by B.

  Observer A is dead


Give that student an A! I bet (s)he was the only one that got the frequency heard by Observer A correct.
