The velocity was easy but I am 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.
 
im not in calc based phy
 
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).
