I just need help with the last two rows, ram angular velocity and ram angular acceleration. I have the rest of the sheet filled out, what equations should I use for the last 2 rows?

Hint(s). ? To facilitate the Richardson method implementation, you may find it helpful to insert two rows before the 0 degree angle value and add two rows after the 360 degree angle value as shown. ? The values of these added lines will not be plotted. ? Your spreadsheet layout, the values will not necessarily be the same, should look similar to what is shown below. Angular velocity w = 1750 rpm 10500 deg/s Time increment = ? S Ram minimum position 93min = ? deg Data Point Crank Ram Crank Angle Angle Time Ram Angular Displacement Index 0 (deg) 03 (deg) t(s) 03 - 03min (deg) Ram Angular Ram Angular Velocity W3 (deg/s) Acceleration a3 (deg/s) Don't plot 350 86.3 0.03333 14.5 2852.5 these rows 355 87.7 0.03381 15.9 2852.5 1 0 89 0.00000 17.2 2712.5 -107187.5 2 5 90.3 0.00048 18.5 2747.5 -64312.5 3 10 91.6 0.00095 19.8 2625 -269500 72 355 87.7 0.03381 15.9 2852.5 -202125 73 360 89 0.03429 17.2 2712.5 -107187.5 Don't plot 5 90.3 0.00048 18.5 2747.5 these rows 10 91.6 0.00095 19.8 2625
