You are hiking out in California and come across an abandoned mine shaft. Wondering how deep the mine shaft is you toss a rock in and it takes 5.1 seconds before hitting the bottom. How deep is the mine shaft in meters?

• Physics -

Depth = (1/2)*g*t^2

g is the acceleration of gravity.

The time it takes the sound to be heard is being neglected, but should be included for a more accurate value for the depth.
