A passenger car weighs 18kN. Its frontal area is 1.9m2 and the aerodynamic drag coefficient is 0.36. The coefficient of rolling resistance is given by f_r=0.012+0.410^(-7) V^2, where V is the speed of the car in km/h. Estimate the maximum engine power required to accelerate the car at a constant rate from standstill to a speed of 100km/h in 6s on a level road with 0 wind speed. The mass factor _mat the highest gear of the transmission is 1.08 and the average transmission efficiency is 0.9
