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

Yeh thanks i got it

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

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.

Yh sorry this was my first post but thanks anyway
