Homework Statement
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
Homework Equations
H = (v0^2 - v1^2)/2g
v1 = v0 - g(t2 - t1)
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.
