Suppose you could dig a tunnel through a diameter of the earth. On one end, you drop a ball in the center of the tunnel opening. What happens next?
Assume:
- spherical, gravitationally homogeneous earth
- no coriolis effects
- no molten interior - solid all the way through
- no magnetic field effects
- to tidal interactions with the moon, sun, etc.
- a vacuum in the tunnel - no aerodynamic effects
