John Salek-Raham Physics 151 Lab M5 10/23/07 Newton’s Second Law Section V-3 : In this section, acceleration was found using the table from the data sheet for each value of M. Then, a plot of acceleration (a) versus M2 was made. Using the slope from the graph, g was calculated. See attached Data sheet for the Data tables: The values of sigma(delta t) were calculated using excel. Acceleration was then found according to equation 1a from the lab manual.

Using excel, the slope of a line that passed through the origin of the plot of a vs. M2 was found to be 1.53 cm s^-2 /g. Solving equation 6 in the lab manual for g:
