A man drops a rock into a well. The man hears the sound of the splash 2.40 s after he releases the rock from rest. The speed of sound in air (at the ambient temperature) is 336 m/s. How far below the top of the well is the surface of the water?

A man drops a rock into a well. (a) The man hears the sound of the splash 2.32 s after he releases the rock from rest. The speed of sound in air (at the ambient temperature) is 336 m/s. How far below the top of the well is the surface of the water? _________ m (b) If the travel time for the sound is ignored, what percentage error is introduced when the depth of the well is calculated? __________%

A rock is dropped from rest into a well: (a) The sound of the splash is heard 2.40 seconds after the rock is released from rest. How far below the top of the well is the surface of the water? The speed of sound in air (at the ambient temperature) is 336 m/s. (b) What If? If the travel time for the sound is neglected, what percentage error is introduced when the depth of the well is calculated?
