Inspect the Picket Fence in the picture below. Dropping it through a Photogate will provide data to determine g. Since the distance, measured from one edge of a black band to the same edge of the next band, is 5 cm. What additional information will you need to determine the average speed of the Picket Fence as it moves through the Photogate?

This data in the table shows the result from the calculation of Pi. Identify this answer in standard format.
