Easy! the formula is Gravity x Time(seconds) = Acceleration, gravity pull is basically 9.8m/s^2 (im not sure how to put squared so i used "^2" to symbolize it) and so basically if you drop a rock on a cliff count how many seconds it takes before it hits the ground, lets say that the rock took 8.5 seconds to hit the ground so you use the gravity pull and times it by the seconds which would be 8.5s x 9.8m/s^2= it is 83.3 meters deep
yes, weight plays a role in how fast an object can fall
It will fall just as fast as an object of any other mass - assuming that air resistance is negligible. That is to say, if an object has a lot of surface area, it will fall slower due to air resistance.
By its size
You need the amount of time that it took to fall the 45m.
An object's top speed is called Terminal Velocity.The terminal velocity of an object can be calculated via a formula. See the related links.

9.6 m/sec2.

45.5 mph
if an object is lightr it will fall slower because gravity wont take it down as fast if it is heavier it will make the gravity pull it down faster
Depend on if you are talking a "free-fall" or an object descending the side of a mountain. Free-fall all objects regardless of weight fall at the same rate of speed (36 feet per second).
No, because you can predict if an object will sink or float mostly on density.
not necessarily, due to wind resistance and the surface area of said object the object will not always fall as fast. ex. a human sky diving. if they are in a pencil dive, they will fall a lot faster then if they are in a spread eagle position. but due to its mass it will sure as hell hurt a lot. so yes and no
By its size
The object will accelerate.
