1. The problem statement, all variables and given/known data The problem lets us graph and give values for s(m) (distance) t(s) time and delta t (s) velocity. After plotting my second graph (including error bars) I used it to get the slope and the acceleration. But then it asks to determine the experimental error. Is there any formular for that? And how should I do it? 2. Relevant equations That's what I want to know. 3. The attempt at a solution Havne't done anything because I don't know what equations. It's urgent please help!
