Question

Why does time = 2h/g?

h = height
g = gravitational acceleration

Answer 1

Step-by-step explanation:

I assume you meant to type t = √2h/g and you're referring to an object in free fall: If so, here's my answer:

x = x₀ + v₀t + 1/2at²

for an object in free fall x - x₀ = h (height the object falls)

v₀ = 0 (if the object starts at rest)

a = g

Therefore,

h = 1/2gt²

t² = 2h/g

t = √2h/g
