A 1:6 scale model automobile is tested in a wind tunnel in the same air properties as the prototype. The prototype automobile runs on the roads at a velocity of 50 km/hr. For dynamically similar conditions, the drag measured on the model is 300 N. Make calculation for the drag of the prototype and the power required to overcome this drag.
