Domino Book Velocity: Data and Analysis

The lab we did on Tuesday July 18 at Barnes and Noble was to set up a line of books like dominoes, knock down the first book, and then time the movement of the disturbance as it travelled to the 5th, 10th, and 15th books. We are trying ti determine if this disturbance travels at a uniform speed and what that speed is.

Here is the data we took:

Distance from start (books)	Time, Trial 1 (sec)	Time, Trial 2 (sec)
0	0	0
5	0.6	0.5
10	1.0	1.1
15	1.2	1.4

Here is what you are expected to do:

Make a cover page which has the title of the lab, your name, the date of the lab, and a diagram of the lab set-up with labels.
Graph the data on one graph, making sure you

mark the axes evenly and label them
at first, plot only the data points (points -- NOT bars!) without any connecting lines
draw the best-fit straight line on your graph
determine how good the fit is (find the correlation coefficient if you are able)

Find the slope of the graph line in books/sec. This represents the average speed of the disturbance.
Error Analysis: Determine how accurate this lab was. Say why.
Describe, within the limits of accuracy of this lab, whether our results are consistent with the hypothesis that the disturbance travels at a constant speed.
