**On the Moon the acceleration...**

On the Moon the acceleration of freefall is 1.7 m s-2. How much time would it take for a featherto fall a distance of 1.0m from rest?

Im not bothered about the answer i just need to know what formula(s) to use

and how.

These are the formulas i was given:

v = u + at

x = ut + 1/2 at^2

v^2 = u^2 +2ax

Average velocity = Displacement / Time

Average Velocity = (v+u)/2

u= initial velocity

a= acceleration

x= displacement

v= final velocity

t= time
