A rocket is launched from a level ground following the path given by y=x−x^3/90, where x is the horizontal position and y is the vertical position. If the magnitude of its horizontal speed (km/min) is always equal to its horizontal position (km), find the final velocity and its angle from the horizontal as it hits the ground.
