Joe recently opened a restaurant and bought a car that has a clean drag area CDA of 3.25 m² and rolling resistance of 700 N at sea level. If he mounts an advertising board as shown in Figure 1, determine the amount of fuel money required per year without the advertising board and the additional amount if the board is installed. The car is estimated to driven 20 000 km a year at an average speed of 50 km/h. Take the density and price of unleaded 95 petrol to be 0.85 kg/h and R 17.12, respectively. Also, consider the density of air to be 1.23 kg/m³, the heating value of 95 petrol to be 46 000 kJ/kg, and overall efficiency of the car's drive train to be 30%. 1.8 m Eat at Joe's Figure 1 0.8 m
