The vehicle with parameters as given in Exercise 2.2 accelerates from 0 to 60 mi/h in 13.0 s for the two following acceleration types: constant FTR and uniform acceleration.

(a) Plot, on the same graph, the velocity profile of each acceleration type.

(b) Calculate and compare the tractive energy required for the two types of acceleration. Ftr=const.=1548 N


(b) etr=0.2752 MJ for constant Ftr and ejr=0.2744 MJ for uniform acceleration.
