Question
When an object moves through the atmosphere it must overcome a force called aerodynamic drag, which exerts itself against the object. The drag force is given bythe following equation:
F = .5*Cd*A*?*V2
where F is the force ( newtons ) on the object that acts to retard its motion, Cd is an experimentally-determined number called the drag coefficient, A is the projected area of the object perpendicular to the direction of motion ( square meters ), ? is the density of the atmosphere through which the object moves (kilograms per cubic meter ), and V is the object
