Question

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 = 4.4 s after you drop the rock. The speed of sound in the well is v_s = 344 m/s. A) Enter the quadratic equation for the distance, D, in terms of the time, the acceleration due to gravity, and the speed of sound. Arrange the expression so that the coefficient of the D^2 term is 1. B) Solve the quadratic equation for the depth of the well, D, and calculate its value in meters.

Step 1

The rock falls down the well, and then the sound of the splash travels back up the well. The time it takes for the rock to fall down the well is t1 and the time it takes for the sound to travel back up is t2. We know that t1 + t2 = t = 4.4 s. The distance the Show more…
