dropping balls
If you were to drop two racquetballs, one filled with lead and the
other normal, off of the Sears Tower, which one would hit the ground first? A) neglecting air resistance B) including air resistance C) Does the answer change for either A or B if one ball is many orders of magnitude heavier then the other. I was wrong the first time I tried to answer this question, and it spawned a 100+ post thread at another forum.
