Explanation:
Given that,
An object in free fall will fall d feet in t seconds, where d and t are related by the algebraic model as :
..........(1)
(a) We need to find the time taken by the object to fall 1148 ft. Put this in equation (1) as :
t = 8.47 seconds
(b) If the object is in free fall for 18.5 sec after it is dropped, then the height of the object is given by :
d = 5476 ft
Hence, this is the required solution.
