Each row of the spreadsheet below contains the position of a particle at a given time. The times are stored in column B, and the corresponding positions in column A. Column C should contain the average rate of change between two consecutive rows. To compute these rates of change, you will write a formula in cell CW and copy it to cells C2, C3, C4, and (35. Assume all cells not shown below are blank position time average rate of change A B C a)What formula should you write in C1? 0 (nan/(52431) O =(B2B1)/ (A241) 0 =($B$2-$B$1) / [$Jk$2-$A$1) O ($A$2$A$1)/E$B$2$B$1) O =(A2-A1J/ (32131) 0 (B2B1)/(A2A1) O ($B$2-$B$1) / CMSZt'pl) =($Jt$2-$A$1) / {$B$2-$B$1) b) Suppose you copy the formula from Cl to cell CG.
