Let the distance be s in feet. i.e, where t is in second.
You drop a rock from a bridge that is 75 feet above the water.
Use the expression to solve for t:
Given: s =75 feet
then, substitute in the above expression:
or we can write it as:
or
⇒ t = 2.16506351 or t ≅2.17 second
Therefore, the rock hit the water in t≅2.17 second
