(When making the graph, be sure to use the numbers you entered in the above table with no additional rounding or decimal places.) Use the trendline option to draw the best fit line to your data and determine the slope and y- intercept. What are the slope and y -intercept of the plot of m 1 g versus acceleration? 1.165 2.426
Page 2 of 5 What is the percent difference between the value of M obtained from the slope of the graph and
What is the total mass as calculated from the slope?
What is the physical significance of the y -intercept? What is the total mass M of your system as determined from the mass of the cart, weight hanger and added masses?
