A 1:8 scale tractor model is tested in a pressurized wind tunnel. The width, height and length of the model are 0.305 m; 0.476 m; and 2.48 m. In the test with a wind speed of 75 m/s, the drag force that occurs in the model is 128 N. Determine the aerodynamic drag and the power that the engine must give to the prototype tractor vehicle when running at a speed of 50 km/hour where the wind blows from the front of the tractor at a speed of 10 km/hour.
