E.g. Between t =0sand t = ... s the acceleration is... (b) Verify that the ball is in free fall by selecting an appropriate region (of the velocity vs time graph) and obtaining the acceleration by applying curve fit, selecting a linear relationship. [2 Points] (c) In a few sentences, attempt to make a reasonable justification as to why obtaining acceleration by fitting a region is more realistic than selecting a single value from the data table.
