An electric vehicle has the following parameter values:

m=800 kg, Cd=0.2, Af=22 m2, Co=0.008, Ci=1.6*10"6 s2/m2

Also, take density of air =1.18 kg/m3, and acceleration due to gravity g=9.81 m/s2.

The vehicle is on level road. It accelerates from 0 to 65 mph in 10 s, such that its velocity profile is

(c) Calculate the energy loss due to nonconservative forces Eo

(d) Calculate eTR.


(a) From the force balance equation, given by v(l) = 0.29055** tor 0 S t £ 10 s
