2. Calculate the slope of the line in your graph of the square of the period of the pendulum vs. length of the string [slope = (y2 – y1)/(x2 – x1)]. Galileo figured out the equation that describes the behavior of a pendulum. If you square both sides of the equation, you will find that the slope of the line is related to the acceleration due to gravity (g). Specifically, slope = 42/g. Use your data to calculate g. How does it compare with the accepted value of 9.807 m/s2? Calculate the percent error and show your work.
