Question 645518
the height of the building is 1176 feet.
 how long would it take an object to fall to the ground from the top?
 use the formula s=16t^2, where s is the distance, in feet, traveled by an
 object falling freely from rest in t seconds.
:
When the objects hits the ground s = 0 ft
:
16t^2 - 1176 = 0
16t^2 = 1176
t^2 = 1176/16
t^2 = 73.5
t = {{{sqrt(73.5)}}}
t = 8.5732 sec to hit the ground
