Tanks have WAY more air friction than bombs because they're bigger, therefore they fall just as fast or maybe even slower than bombs.
try this:
take an office sheet of paper and make it a ball, now tak a newspaper and dont wrap it drop them both at the same time form some height the newspaper held flat offcourse, and youll see that the "balled" office paper flas faster if you did it right...
enough physics lessons for today.
