A one tenth scale model of a soap box derby car is tested in a wind tunnel. The air speed in the wind tunnel is 70m/s, the air drag on the model car is 240 N, and the air temperature and pressure are identical to those expected when the prototype car is racing. Find the corresponding racing speed and the drag on the car.
