The problem is you drop a coin into a well then 3 second later you hear the splash. With this information find out the height of the well.

Assume 343 m/s is the speed of sound and neglect any effects due to air resistance.

g = acceleration due to gravity = 9.8 m/s^2

v0 = initial velocity = 0 m/s

v1 = final velocity

H = height

t1 = initial time = 0 s

t2 = time at final velocity

2. Relevant equations

H = (v0^2 - v1^2)/2g

v1 = v0 - g(t2 - t1)

3. The attempt at a solution

Reduced equation to H = v0^2/2g and found v0 to be -9.8m/s^2(3s - 343m/s(t2))

I'm mainly having trouble trying to find out how much time was taken off for the sound of the splash reaching you.

Any help is appreciated.
