A stone is dropped into a well. The sound of the splash is heard 2.30 s later. What is the depth of the well?
g = -9.8 m/s^2
Vsound in air = 343 m/s
The Attempt at a Solution
I'm not really sure how to start. I know that the time it takes to drop down + the time it takes the sound to go back up must = 2.3 seconds
