1. The problem statement, all variables and given/known data

ball thrown horizontally from roof of building 55.0m tall and lands 29.7m from the base. find balls initial speed

2. Relevant equations
(√acceleration/[√2*55] ) * 29.7=8.86

3. The attempt at a solution
(sqroot acceleration/[2*55] ) * 29.7=8.86
the answer is correct..I am confused how it is that i can get to this formula.

I am confused to what "29.7m from the base" means
thanks all
*this is my first time posting, I hope i am doing it correct
