- How much energy is required to lift a 10 kg rock from the surface of the Earth and place it in a circular orbit just 10 km above sea level? Assume Earth's radius is about 6371 km.A satellite of mass 2,134 kg orbits the Earth at an altitude of 3,434 km in a circular orbit. How many hours does it take for this satellite to complete one full revolution? Mass of the Earth: kg. Mean radius of the Earth: 6370 km.A satellite has an orbital speed of 4.28 x 10^3 m/s.What is its altitude above Earth’s surface?What is its gravitational energy?
- Use Kepler's third Law to determine how many days it takes a spacecraft to travel in an elliptical orbit from a point 6670 km from earth's center to a point 385,000 km from earth's center(the mass of earth is 5.97*10^24 kg).An astronomer observes a planet orbiting a star with a period of 8.7 years and a semimajor axis of 2.7 × 10° km. Find the mass of the star. The universal gravitational constant G = 6.673 × 10-11 m³ kg¬1 s-2.A satellite is orbiting the earth in low orbit (160 km above the surface of the earth). If the universal gravitational constant is 6.67 x 10^-11 m^3/kg x s^2 the mass of the earth is 5.972 x 10^24 kg and the radius of the earth is 6371 km, what speed must the satellite travel in order to maintain the low earth orbit?
