2. Now consider the solution in Problem 1.3 vtanhwhen 1)when 2. Now consider the solution in Problem 1.3m=681kgtanh c = 0.22 kg/s Calculate the new velocity as a function of time for 0 sts 12 s. Then calculate the relative error between these results and the results to Post-Lab problem 1 (where c 12.5 kg/s). Plot the velocity vs. time curves for each model in the same window, and overlay a plot of the relative error vs. time. Assume that the Fcv model represents the "true" model. (Remember to use the "hold on" function in MATLAB for plotting) 2. Now consider the solution in Problem 1.3 vtanhwhen 1)when 2.
