A man drops a rock into a well. He hears the sound of the splash 3.2 seconds after he releases the rock from rest. The speed of sound in air (at the local ambient condition) is 338 m/s.
(a) How far below the top of the well is the surface of the water? (round your answer to a whole number)
(b) If you ignored the travel time for the sound, what would have been the calculated depth? (round your answer to a whole number)
