How do I find the velocity from this data set?

More detailed instructions are in the sections below. Hint: For this activity, it's important to use evenly spaced time intervals for your position measurements. Since the entire motion takes about 0.7 seconds, we'll measure the position of the ball every 0.05 seconds so we'll get about 14 measurements.
