Imagine we have taken position-time data for a running rabbit.

Start Logger Pro on your computer and type the data into Logger Pro. Graph the points and then fit a curve to the data (Analyze >> curve fit). Try successively higher polynomials until the data are well fit, but no higher. From the fit, determine the velocity and acceleration as a function of time. Graph and discuss. Does the rabbit hop?
Hint: If you select create calculate column in the Curve Fit box, you will get a new data column with the computed Y-values, and you will have access to the coefficients of the polynomial fit. Use these you to calulate v and a.
