If there were no air resistance, a quarter dropped from the top of New York's empire state building would reach the ground 9.6 seconds later, what would its speed be? How high is the building?

distance = 1/2*g*t^2
velocity = g*t 
I don't know how to use those formulas to figure out what the speed and how high the building would be ?

distance = 1/2*g*t^2
distance is what you want.
1/2 is obvious.
g = 9.8 meters/secnd/second
t = time = 9.6 seconds in the problem. Solve for d. 
Okay, thank you! I'm pretty sure I got it! What about to know how high the building is though? Sorry if you already answered that too, I am awful with this kind of stuff

The distance IS how high.
