A second experiment was carried out where the vehicle speed was recorded and display graphically below. Taking the variables t and s to represent elapsed time in seconds and vehicle speed in km/hr write down the required lines of code in Matlab to compute the acceleration of the vehicle in m/s Speed [km/hr] 60 50 40 30 20 10 0 0 5 10 15 Elapsed time [s] 20 25 30 Write down the additional lines of Matlab code to calculate and plot the rolling resistance coefficient of the vehicle as a function of vehicle speed.
