Explanation:
It is given that, the height of a certain tower is 862 feet i.e to reach on the ground the object should travel, s = 862 feet
The distance traveled by a freely falling object is given by :
[tex]s(t)=16t^2[/tex]
[tex]16t^2=862[/tex]
[tex]t=\sqrt{53.875}[/tex]
t = 7.34 seconds
So, the object will take 7.34 seconds to fall to the ground from the top of the building. Hence, this is the required solution.
