    Abstract Ducted rocket has been widely concerned on account of its high specific impulse, combustion stability and convenient maintenance which mixes the exhaust from a fuel gas generator with air from air inlet, and burns to produce thrust.   In contrast, a waverider whose shock angle decreases as a parabolic curve along the spanwise direction has a smaller volume and higher lift-to-drag ratio. Providing different shock angle distributions can lead to greater flexibility in the design and optimization of hypersonic waverider vehicles.

    A model rocket is launched from a roof into a large field. The path of the rocket can be modeled by the equation y = x^2 + x + 5, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. How far horizontally from its starting point will.
