Answer: t = 7.85seconds
Step-by-step explanation:
Given that :
Height of tower = 986 Feets
Function s(t) = 16t^2
To find the time t 8 in Seconds taken for an object to fall to the ground from the top of the building
16t^2 = 986
t^2 = 986/16
t ^2 = 61.625
Take the square root of both sides
t = sqrt(61.625)
t = 7.85seconds
