A student drops a book, a flat sheet of paper, and a balled-up piece of paper from a height of 1.5 m (IN A VACUUM, NO AIR). They use a timer to determine how long it takes each object to hit the ground. Which results are the most accurate?
The balled-up and flat sheets of paper both fell faster than the physics book because they have less mass.
The balled-up and flat sheets of paper both took longer than the physics book because they have less mass.
The balled-up and flat sheets of paper both hit the ground at approximately the same time as the physics book.
The balled-up sheet of paper hit the ground at approximately the same time as the physics book. The flat sheet took longer to fall due to air resistance.
