A ball is dropped from a roof and takes 3.0 s to reach the ground. Calculate the elevation of the roof above the ground in meters.

h=1/2 g t^2 solve for h

h = 1/2 (9.81) (3^2)
h = 44.14 meters 
Yes

Solve: an iron ball is dropped from the roof and it takes 3second to reach the ground.calculate the elevation of the roof above the ground.
