An electric vehicle has the following parameter values: m, = 1000 kg Cb=0.24 A= 2.1 m² g= 1.22 kg/m³ 0.008 +0.6x10x (r. vehicle speed in m/s) The vehicle is on level (flat) road. It accelerates from 0 to 100 km/h in 10s such that its velocity profile is given by r(t) = 0.29055t² for 0 < t < 10s. (The mass factor is assumed unit) a. Define the traction force expression F b. Sketch F, versus time (approximately) c. Define the instantaneous traction power expression d. Calculate the energy consumed during the acceleration (0 < t < 10s) e. Calculate the energy lost for non-conservative forces (wind and rolling resistances) f. Find the change in kinetic energy and the change in tractive energy during acceleration An electric vehicle has the following parameter values: m, = 1000 kg Cb=0.24 A= 2.1 m² g= 1.22 kg/m³ 0.008 +0.6x10x (r. vehicle speed in m/s) The vehicle is on level (flat) road.
