You are exploring a distant planet. when your spaceship is in a circular orbit at a distance of 630 km above the planet's surface, the ship's orbital speed is 5500 m/s . by observing the planet, you determine its radius to be 4.48×106 m. you then land on the surface and, at a place where the ground is level, launch a small projectile with initial speed 14.6 m/s at an angle of 30.8∘ above the horizontal. if resistance due to the planet's atmosphere is negligible, what is the horizontal range of the projectile?
