Physics Experts?

Hey all, I got stuck at this physics question. Looking for help. It's kinda hard, well for me at least. A stone is dropped into a well. The sound of the splash is heard 3.0s later. What is the depth of the well ? (Assume the speed of sound is 340m/s). When the rock drops, it goes uniform acceleration but when you hear the sound, it is uniform motion...That's the hard thing about the question. Too many unknowns for both equation. Am i missing something here? Thanks in advance

I just wanted to see if I can still think after being sucked into the workforce for the last 2 years... :~ I do have a life, I promise! :rolleyes: - Nitron

Looks like a better/quicker version of your's. I may have to try my Physics master on this one. He always likes a challenge.

Mass of the stone? Neglagable air resistance?

Don't forget to take into account the kittens tied up in the sack causing air resistance on the stone. :~ :laugh:

Paul Watson, on Sports - 2/10/2003Yeah yeah, i know, my physics master would have shot me. I've been revising 'motion' for my physics AS exam, F=dp/dt is running through my brain too much when I should be thinking of the motion equations. Damn me,damn me.....i realised soon after posting that that the mass is not needed.
