Part 2 - CalculationsUse Excel to create a graph of m1gversus acceleration. (When making the graph, be sure to use the numbers you entered in theabove 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 m1gversus acceleration?Key:Answers may vary.Score: 5 out of 5Comment:Your answer cannot be understood or graded.
