    I am not sure how to calc. the inst acc....
    The velocity was easy but im not sure about the acceleration???/

    Acceleration is the rate of change of velocity.

    ok for velocity I got 10.1 m/s and 10.25 m/s .....
    so substract them is what you are telling me?

    Both are functions of time, so just subtracting them will not be sufficient. Do you know a function for acceleration you can use? You can obtain it by taking the derivative of the function for velocity.

    I see, sorry about that.

    Here's some information that you can use to solve this problem. I don't want to tell you too much because it is good for you to think about it. :smile:

    a=(v-vo)/t

    where

    a=acceleration (m/s2)
    v=final velocity (m/s)
    vo=initial velocity (m/s)
    t=time (s).
