(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A stone is dropped from rest into a well. The sound of the splash is heard exactl 2.00 s later. Find the depth of the well if the air temperatrue is 10.0 degrees Celsius.

2. Relevant equations

Possibly the Kinematics Equation

V= Vo sqrt(1+Temp/273)

3. The attempt at a solution

First i found the speed of the sound and came up with

v = 337.0 m/s

i used the kinematics equation to find the time it took for the stone to hit the bottom of the well and it is

Tstone = sqrt(2x/g)

so i the total time equals the time it takes for the stone to hit the ground and the sound to come up so

2.0 s = x/337 + sqrt( 2x/9.8 ) where x equals the depth of the well

I don't think it is right, and I can't seem to solve for x. Can anyone help? The answer should be 18.5 m
