A man drops a rock into a well.
(a) The man hears the sound of the splash 2.40s after he releasesthe rock from rest. The speed of sound in air (at the ambienttemperature) is 336 m/s. How far below the top of the well is thesurface of the water?
(b) What if the travel time for the sound is ignored, whatpercentage error is introduced when the depth of the well iscalculated?

You stand at the top of a deep well. To determine the depth ( ) of the well, your drop a rock from the top of the well and listen for the splash at the water hits the surface. The splash arrives   after you drop the rock. The speed of sound in the well is .

A) Find the quadratic equation for the distance D in terms of time, the acceleration due to gravity, and the speed of sound. Arrange the expression so that the coefficient of the term is 1. 

B) Solve the equation for the depth of the well in meters.

Trying to determine its depth, a rock climber drops a pebble into a chasm and hears the pebble strike the ground 3.74 s later.
