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)0.0501.20000.25001.78870.43940.1001.23000.32401.62010.68040.1501.15000.38201.46360.88140.2001.11000.42401.38181.0714where m1is the value of the hanging mass (including the mass of the hanger), v1is the averagevelocity and t1is the time at which v1is the instantaneous velocity for the first photogate, and v2is theaverage velocity 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.
(b) Use the information you obtained from your graph to determine the total mass of the systemM= m1+ m2.Lab 3 - Newton's Second Law: PostLab (PostLab)Karim GhanemPY 211, section 201, Fall 2011Instructor: Robert A.
