Moon Experiment (Posted on 2004-11-22) Difficulty: 5 of 5
Assume the moon is a perfect sphere and a straight tunnel has been drilled through the center. How long would it take a 1kg ball dropped from one end of the tunnel to reach the center? Ignore all resistances.

If a second 1kg ball is dropped 10 seconds after the first one, when and where in the tunnel would they first meet?

Idealized Moon Stats:
- Diameter: 3480 kilometers
- Mass: 7.38x10^22 kilograms (uniform density)

(In reply to too hard by GOM)

I agree that this is way too hard. I also think that if you did this on Earth, the ball would come out in China, upside down. I learn most of my science from Bugs Bunny cartoons.

I also know that if you shoot a duck in the face with a shotgun, his bill gets spun around.

Also, coyotes have the capability to order explosives and other destructive devices and recieve the weaopns in a matter of seconds. this seems like a national security threat to me, especially since the Coyote hasnt eaten in 50 some odd years. The ACME corporation probably has some ties to the Taliban, as well as the French (God I hate the French)
