You are exploring a distant planet. When your spaceship is ina circular orbit at a distance of 630 km above the planet’s surface, the ship’sorbital speed is 4900 m/s. By observing the planet, you determine its radiusto be 4.48 * 10^6 m. You then land on the surface and, at a place where theground is level, launch a small projectile with initial speed 12.6 m>s at anangle of 30.8 above the horizontal. If resistance due to the planet’s atmosphereis negligible, what is the horizontal range of the projectile?
