    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?

    Start with the acceleration. Integrate twice.

    just integrate the acceleration twice...?
    I tryied aleady...but it makes no sense....
    I don't get it....

    Show what you did. Since [itex]a = dv/dt[/itex], 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....
