maksim [4K]
Given: Height h = 6 ft  or the vertical component "y" this become the initial height, therefore if you want to know the total height of the stone with respect to the ground. you can just add up the two value below.

           Initial Velocity Vi = 41 ft/s     g = -32.2 ft/s²  acting downward

Require: Height h = ?       

Formula: y = Vf² - Vi²/2g

               y = 0 - (41 ft/s)²/2(-32.2 ft/s²)

               y = -1,681 ft²/s²/(-64.4 ft/s²)

               y =  26.10 ft
