This console application models a mathematical equation to determine the power in watts and horsepower needed to overcome the drag force produced on a car based upon its velocity.
Constants are obtained from laws of physics where rho is the density of air (1.23kg/m^3), v is the velocity in units of m/s, A is the projected area of the vehicle (2.5m^2), and C sub D is the drag coefficient (0.2). Conversions are applied as 1 mph = 0.447 m/s.
