Extension: Air Resistance Model Incorporating Air Density

A projectile model building on Challenge 9, which considers projectile motion in an atmosphere with a model of air density that diminishes with altitude. T he original air resistance model (red) can be compared with the new model (orange) along with the drag-free model (purple).
In order to see the difference between the orange and the red, the streamlined body setting works best.
