I would expect you to have seen $s(t)=\frac{1}{2}at^2+v_0t+s_0$?

Yeh thanks i got it

 

[mouk92]

When i was doing it i was squaring the whole of the at instead of just the t

 

[Cyosis]

I see. You should really put that in the relevant equation section, that way people reading this forum could have seen what went wrong right away.
