Just like getting a BJ from grandma... don't look down.

Amazing. I'm gonna start a second career as a cave explorer right away.
Is this the cave where the Chinese Government dumps all the executed people? It shouldn't be that deep anymore... |
Should we tell Sheldon there is a giant vertical shaft in the IotD?
I just did some calculations, and if I got them right, if you tossed a stone into that shaft it would take 14.5 seconds to hit the bottom. There would be another three seconds before the sound reached you back at the top. When it hit it would have been doing 510 kph (317mph) less wind resistance. |
I thought terminal velocity was around 200mph?
|
Obviously the work of a big Horta with locomotion difficulties.
|
It's really cool how smooth/straight that hole is. I'm no geologist. There's probably some simple explanation for how it was formed, but I can't imagine what that would be.

I just want to throw a hot dog down there. Zen can calculate it for me. And Sheldon could laff.

What about terminal velocity? I guess you couldn't figure it unless you knew the exact size & mass of the stone and figured out the air resistance.
|
All you really need is the mass, frontal area and drag coefficient.
