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
