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 My memories from school by Brian Wainscott)

Even if the two holes where only an inch appart?.

I guess this could be true, since the projection of the acceleration in the direction of motion is tiny for two holes wich are close together.

Interesting.
