1.246. The car with an area of a midship section (the greatest area of section in the direction, perpendicular speeds) S = 2,2 sq.m, coefficient of front resistance of Skh = 0,4 and the maximum power of P = 45 kW can gather on horizontal sites of the road speed to 140 km/h. At reconstruction of the car reduce the area of a midship section to S1 = 2 sq.m, leaving Skh former. Accepting friction force about a surface of the road of a constant, to define, what maximum power the car that it gathered on horizontal sites of the road speed to 160 km/h has to have. Density of air to accept equal 1,29 kg/m3.
