A car on a perfect level surface in still air goes 120 mph using 200 hp. measured at the rear
wheels. An airplane flies directly over the car maintaining exactly the same speed. They both
turn into a 20 mph headwind. What happens? (Give the speeds of both after the turn.) Assume: 1.
The car and the plane apply constant power to the world, before and after the turn. The carââ¬â¢s
transmission has to allow the same power to be developed regardless of speed. 2. The plane files
low so IAS = TAS if that matters. 3. There are no interactions between car and plane. 4. Ignore
turning effects and loss of energy by the plane in the actual turn, we are interested in
steady-state results long after the turn. 5. The car has very very low drag tires so that all the
drag on the car is aerodynamic.
