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=3.5 s after you drop the rock. The speed of sound in the well is vs = 344 m/s. Part (a) Enter the quadratic equation for the distance, D, in terms of the time, the acceleration due to gravity, and the speed of sound.
