A high-performance car has a drag coefficient of 0.37 and a frontal area of 2.44 m2. The effective mass of the vehicle and driver is 2000 kg (4409 lb), and the ambient conditions are an air temperature of 20°C (68°F) and a pressure of 101.325 kN/m2 the speed range 100-200 km/h (62-124 mph), the rolling resistance is 340 N and the mean torque at the rear wheels is 1123 Nm; the effective diameter of the tires is 0.58 m (1.9 ft). Show that if the drag coefficient were reduced to zero, there would be a 29% reduction in the 100-200 km/h (62-124 mph) acceleration time.
