5=(0)t+0.5at^2
t=2 solve for a
a= 2.5
there is not enough info if the acceleration is dependant on distance form the earth

That can't be right, because you don't account for the distance travelled during the first second.
OK here you go:
a = (Vf - Vi)/t
Vi=0
Vf -- you know it moves 5m during the second second, so 5m/s is it's
average velocity during the second second, which means it's actual velocity is 5m/s
half way through the second second. Therefore:
a = (5m/s - 0)/1.5s
a = 5m/s/1.5s
a = 3.33m/s/s [/b][/quote]
Yes! Thankyou!
This damn question has been bugging me all day.
