Determine the acceleration of a cart on a track

Your goal in this experiment is to determine the acceleration of a cart as it rolls down a tilted track.

Last time, you measured the time it took a cart to roll certain distances down a tilted track. Today, you must analyze those measurements to figure out the average acceleration of the cart.

You should have a table of measurements that looks something like this:


                                                                        2    2
Distance (cm)        Time to roll (s)       avg time (s)      (avg time)  (s)
                         
                     1       2       3             +/-                +/-

Use your measurements to make a graph which corresponds to the following equation:

What is the acceleration of the cart? Be sure to include both a value and an uncertainty.

If you have time: Is there any way to compute this acceleration, theoretically? If so, how does the theoretical acceleration compare to your measured value?
