please tell me if the body initial velocity is zero then s=ut + 1/2at^2 i find that time =under root 2s/a but we know that v=s/t and a=v/t then from these two equation time=under root s/a please explainme why the result is different in both the cases

```							here, there is a problem with concepts.
s=ut+1/2att
u=0
so,t=under root 2s/a
a=v/t
till here everything is fine.
v=s/t
here, v=average velocity
this v is not equal to v used above
v used above=instantaneous velocity
