The truck has a drag coefficient of CD = 1.12 when it is moving with a constant velocity of 80 km/h. The average front projected area of the truck is 10.5 m2. The air is at a temperature of 10° C. At this temperature pa = 1.247 kg/m³. (Figure 1) Determine the power needed to drive the truck at this speed. Express your answer to three significant figures and include the appropriate units. P = Value Units
