(7%) Problem 4: You stand at the top of a deep well: To determine the depth, D, of the well you drop a rock from the top of the well and listen for the splash as the rock hits the water's surface. The sound of the splash arrives t = 3.7 s after you drop the rock. The speed of sound in the well is Vs = 339 m/s.
