To optimise the vehicle's ability to coast, the resistance forces are the most important. The main variables are: • Aerodynamic: Coefficient of aerodynamic drag (Cd) • Rolling resistance: Coefficient of rolling resistance (Crr) Assume the following values for other parameters: = = Af = 1.4; % m^2 mveh = 75; % kg Tm = 3; % Nm vlow = 2; % m/s m/ vhigh = 6; % m/s 6/ GR = 6; % no units ; Produce code that determines the value of percentage time for Cd values between 0.08 and 0.3 in steps of 0.01. Set Crr to be 0.002. Show the results by plotting a graph of percentage time on against coefficient of drag (i.e. pcttime as the y-axis, and Cd as the x-axis). The y-axis should have the label 'Percentage Time On (%) and the x-axis should have the label 'Coefficient of drag'. = Script C Reset DE MATLAB Documentation 1 clear 2 = = 3 % Constants, defined in question 4 Af = 1.4; % m^2 5 mveh = 75; % kg 6 Tm = 3; % Nm 7 vlow = 2; % m/s % 8 vhigh = 6; % m/s % 9 GR = 6; % no units 10 11 cd = 12 Crr = 13 14 % Code to find pcttime for all values of varying parameter 15 16 17 % Code to plot solution 18
