Question

Greetings,
I just did a lab where i slide a car down an airtrack and a aprogram makes a Position vs Time graph and a Velocity vs Timegraph.
My information for the Position vs Time graph is as follows: x= At^2+Bt+C A: 0.2532 +/- 0.003159 B: -0.2700 +/- 0.01096 C: 0.4684 +/- 0.009111 RMSE: 0.002434m
edit: x = Position, t = time
How do I find the Acceleration with this information?

Explanation / Answer

Acceleration = Distance/Time Xo = Initial Distance X = Final Distance To = Initial Time T = Final time Acceleration = (X-Xo)/(T-To) Just pick a couple points in the graph and you will get youranswer.
