There are many factors that can affect the time for these objects to drop. The height at which each object is dropped is a factor since the height is proportional to time. if the height at which these objects are dropped are the same, then the time for them to drop to the floor is the same. Since the acceleration due to gravity at sea level is 9.81 m/s^2 for all objects no matter the mass, both objects will accelerate at the same rate which means they will reach the floor at the same rate. All in all, both the pencil and the penny will hit the ground at the same time.
They will both hit the ground at the same time.
Simply use the expression v = gt g = 9.8 m/s^2 and t given as 4.5 s So velocity with which the penny hits the ground will be 44.1 m/s
Theoretically each will hit the ground at the exact same time. Practically, however, the distance from the drop position to the ground is a very impotant factor. If you drop both at a relatively short distance (say 5 feet) they will effectually hit at the same time if they encounter no wind resistance. If you drop them at a much higher distance (say 100 feet) the quarter will hit the ground before the penny. The reason being is resistance to the flat surface of the penny verses the quarter. Since the penny is much lighter than the quarter (a penny weighs 2.5 grams and a quarter weighs 5.67 grams) it will be affected to a greater degree by wind resistance that the much heavier quarter. You can liken it as to a feather being dropped. The feather will flip and twist and float as it slowly drifts down to the ground. The quarter being heavier will drop less reactivly and have a much straighter decent and therefore hit the ground sooner.

nether both will hit at the same time
If a penny and a text book were dropped in a vacuum then they will both hit the ground at the same time. This refers to Newton's laws. If they are dropped at the same time on earth then the text book would hit the ground first.
they will both hit the ground at the same time
They will both hit the ground at the same time.
Depending on the angle that the coins are falling, if they are falling heads down, completely horizontal with the ground, the quarter has more air resistance then the penny, making the penny hit the ground first. If they are on their sides, so the head is completely vertical with the ground, they are both arrow dynamic and the quarter and the penny hit at the same time. as the acceleration of gravity is -9.8 m/s squared, thus making they fall at the same acceleration.
It depends on the paper. If it is large and flat, then it will almost certainly land after the penny. If it is folded up nice and small and dense, then it will hit the ground at about the same time as the penny.

no
Assuming both were dropped from the same height above ground, in a vacuum both would hit the ground at the same time. In a significant atmosphere (e.g. average ground-level on Earch) the bowling ball would hit the ground first.
