A hybrid car with a total mass of m = 1450 kg, aerodynamic coefficient of 0.26, front cross-sectional area of 2,900 m2, gear ratio of 1.23: 1, efficiency 0.85, wheel diameter of 0.4064 m, rolling coefficient of friction of 0.02 Calculate the power and torque required to travel the road with a speed of 140 km / h. The slope of the road is 45 per thousand. What is the energy required to travel the road 500 km with 0 slopes per thousand? When the vehicle moves at a constant speed of 140 km / h on a slope of 0 per thousand, how long does the vehicle stop if the engine and mechanical brakes do not work
