I just forget to show the work when I upload the attachment...
I just know A = V' ....so V = (A^2)/2 + C.....
but what should I do for the Vo?
I really have no clue....can you guys give some hints?

I tryied aleady...but it makes no sense....
I don't get it....

Show what you did. Since $a = dv/dt$, integrating a with respect to t will give you the velocity. That's step one.

yes, I know that....

but there is no function of the accelration respect to time given....

and the acceleration is constant in this question......
I think there must be related to the word "constant"....
and I still thinking....
