Calculate time an object takes to fall to the ground

Description

The time an object takes to fall to the ground (ignoring air friction) is given by the formula
t = √(2h/g)

where
t = time in seconds,
h = height in meters,
g = the acceleration due to gravity, 9.8 m/s²

Example:
Compute the time taken by a stone falling from the top of the Eiffel Tower (300.51 meters high) to the earth.

Manual solution:
300.51 ENTER 2 x 9.8 ÷ √x → 7.8313

Programmed Solution:
300.51 f A → 7.8313
