Answer:
<em>The second drop is 3.75 m above the ground</em>
Explanation:
<u>Free Fall Motion</u>
A free-falling object falls under the sole influence of gravity without air resistance.
If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is
.
The distance traveled by a dropped object is:

If we know the height h from which the object was dropped, we can find the time it takes fo hit the ground:

When the first drop touches the ground there are two more drops in the air: the second drop still traveling, and the third drop just released from the tap.
The total time taken for the first drop to reach the ground is:


Half of this time has taken the second drop to fall:

It has fallen a distance of:


Thus its height is:
h = 5 - 1.25 = 3.75
The second drop is 3.75 m above the ground
