In the automobile industry, the dimensionless drag coefficient and the area of the vehicle are often combined into one variable - the dra area whereby the drag area is the product of the dimensionless drag coefficient and the area (Drag Area = C*A). A Tesla has a drag area of 0.46 m², whereas an SUV has a drag area of 2.45 m². Assuming the desity of air is equal to 1.21 kg/m^3, determine the amount of energy consumed in overcoming drag for: (a) A Tesla cruising at 120km/hr for 20km. select units (b) An SUV cruising at 120km/hr for 20km. select units (c) A Tesla cruising at 90km/hr for 20km.
