Velocity of a falling object?

it is very difficult to mathematically calculate, but a simple experiment can be performed by almost anyone.
You will need:
-1 bowling ball
-2 people, no more, no less.
1) Get Person A to bring with him the bowling ball, and be approximately 15 feet or higher above Person B. Previous users claim using a ladder to get on top of a residential roof gives them a perfect height, but remember to keep safety in mind!
*It is a very good idea to leave all of Person A and B's electronics, cell phones and sharp objects on the ground
2) Once Person A is on the roof, Person B must now remove the ladder for safety reasons.
3) Person A now drops the bowling ball directly above where Person B was standing. Ensure Person B stands still, to accurately record the time without delay. You are now finding the variable "t".
4) Person B will lay on the ground signalling that he recorded the time. It will appear that he is sleeping, but calculations of this precision can be very exhausting. Allow him to rest. Your experiment is now complete, aside from the final calculation.
v is velocity
d is height of roof
t is time ball took to fall.
