Depends on which one is dropped first. If they are both dropped at the same time, they will both reach the ground at the same time.
In a vacuum, there is no drag, i.e. air resistance, so the coin and the piece of paper will fall the same way in a vacuum, whereas in air, the paper will flutter down while the coin will have minimal impediment due to its drag coefficient being far less than that of paper.
In a vacuum, both a ball and a piece of paper will fall at the same rate and hit the ground at the same time because they are subject to the same gravitational acceleration. However, in reality, the paper may experience more air resistance and fall more slowly than the ball.
the sheet of paper,because it has more surface area
If the paper gets away from the book, it creates a vacuum which will suck the paper back against the book. Only if there is a side flow can the "vacuum" be compensated as the paper slowly gets away. In free fall, the fall itself creates a vacuum behind the falling object (book + paper), so that no air is available to compensate the vacuum created by separating book and paper - thus the paper remains sticked. (2 cents assumption)
longer because the stone has less kinetic energy
In vacuum, both the stone and the pencil would fall at the same rate due to gravity and there would be no air resistance to affect their acceleration. Therefore, both the stone and the pencil would reach the ground at the same time.
In a vacuum, a feather and a piece of paper would fall at the same rate due to gravity. However, in Earth's atmosphere, the feather would fall more slowly due to air resistance.
In a vacuum, both the feather and the stone would fall at the same rate due to the absence of air resistance. This is known as the principle of equivalence, where all objects fall at the same rate regardless of their mass.
Faster than on Earth? The reason it falls slowly on Earth is because of air resistance. You can also make it fall quickly on Earth if you make it fall within a vacuum chamber.
Assuming they are both dropped from the same height in a vacuum, they would fall at the same rate and hit the ground simultaneously, as their mass and size do not affect their rate of falling in a vacuum.
If all wind was eliminated, they would both fall at the same time because gravity has a constant increasing rate of pull, not matter how heavy the object might be. Though, because paper is lighter than cloth, and is easily toiled by wind, cloth would fall faster than paper, because paper is affected by wind more than cloth is. The answer could either way.
In a vacuum, both the leaf and the stone would fall with the same acceleration, as they would be subject only to the force of gravity. This is because the acceleration due to gravity is constant regardless of an object's mass.
