A student has two identical sheets of paper. he crumples one up into a small ball. if he drops the sheet of paper and the ball of paper off a building at the same time, which will reach the ground first and why?

Respuesta :

The air resistance acting on the un-crumbled sheet is greater.
The small ball will because air resistance has less effect on it than it does on the piece of paper.  Physics 101 here.  I love Physics!
