An object is dropped from a height h above the ground. this free-falling object requires 1.02 s to travel the last 39 m before hitting the ground. from what height h above the ground did the object fall?

H = 95.3 m

Explanation:

Let the height from which object fall down is H

so the total time to fall is given as

now it cover 39 m in last 1.02 s of its path

so now we have

by solving above equation

Now the total height is given as

H = 95.3 m
