The height of the Empire State Building is 318.00 meters. If a stone is dropped from the top of the building, what is the stone's velocity just before it strikes the ground?

OpenStudy (gebooors):

Starting from rest, distance s which a stone travels, is s = 0,5gt^2 in free fall. Then v = v0 + gt.

OpenStudy (gebooors):

First you need to solve falling time t.

OpenStudy (anonymous):

the answer?

OpenStudy (gebooors):

First falling time t = square root(2s/g) G = 9.8 ms^-2
