10/7/2020 Lab 3 - Newton's Second Law: PostLab - PY 211, section 208, Fall 2020 | WebAssign 3/14 Use the exact values you enter to make later calculations. A group of students performed the same "Newton's Second Law" experiment that you did in class. Forthis lab, assume g= 9.81 m/s2. They obtained the following results:m1(kg)t1(s)v1(m/s)t2(s)v2(m/s)0.0501.20000.25001.76670.48580.1001.23000.32401.61910.68390.1501.15000.38201.46590.87410.2001.11000.42401.38511.0599where m1is the value of the hanging mass (including the mass of the hanger), v1is the average velocityand t1is the time at which v1is the instantaneous velocity for the first photogate, and v2is the averagevelocity and t2is the time at which v2is the instantaneous velocity for the second photogate.(a) Use Excel to construct a spreadsheet to do the following. (You will not submit thisspreadsheet. However, the results will be needed later in this problem.)(i) Enter the above data.(ii) Compute the acceleration, a, for each trial. (iii) Create a graph of the hanging weight m1gvs. the acceleration. (iv) Use the trendline option to draw the best fit line for the above data and determinethe slope and y-intercept from it. (v) report your results below.1.[18.75/25 Points]DETAILSPREVIOUS ANSWERSMY NOTESPRACTICE ANOTHER slope = 0 7696 kg 0 77 kg

(c) Using the information you obtained in parts (a) and (b), predict what the value of theacceleration would be if the value of the hanging mass were increased to m1= 0.40 kg. Your answer cannot be understood or graded. More Information 4.81 m/s^2 Additional Materials Newton's Second Law Appendix
