Earth rotation question?

Monday, February 6th, 2006
sears tower
Mark G asked:


Scenario:
1. I’m standing on the top of the Sears tower.
2. Directly below me in a straight line, there is an X painted on the pavement.
3. There is no wind.
4. I drop (perfectly) a heavy round ball (say the size of a basketball) who’s target is the X.

Question: Will the bowling ball hit the X or will the Earth’s rotation cause a misfire?
