Miike012 Messages 1,009 Reaction score 0 Sep 16, 2011 #3 ok for velocity I got 10.1 m/s and 10.25 m/s ... so substract them is what you are telling me?
Dembadon Gold Member Messages 660 Reaction score 88 Sep 16, 2011 #4 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 don't want to tell you too much because it is good for you to think about it. a=(v-vo)/t where a=acceleration (m/s2) v=final velocity (m/s) vo=initial velocity (m/s) t=time (s).
