The initial velocity of the stone is 0 ft/s. Given the initial velocity (Vi), final velocity (Vf), and acceleration due to gravity (g), the distance may be calculated through the equation,

d = ((Vf) ² - (Vi) ²) / 2g

Substituting the known values,

d = ((96 ft/s) ² - 0)) / (2x32.2)

The value of d is 143.10 ft.
