A space explorer is trapped on the surface of a planet from the movie Interstellar, which has a mass of 11.7×1018 kg and a radius of 4.30×103 km. If the mass of the space explorer is 9.37 kg, what is the minimum speed required for her to escape this planet? Answer in normal form (i.e. not in scientific notation - just add leading or trailing zeros or prefixes as needed).

In the distant future, space explorers from earth discover a new planet. They can measure the radius of the planet to be 7350 km, but they want to know its mass. They observe what the planet has a moon in a circular orbit 32,800 km above the surface of the planet. The moons orbit speed is 3.9 1 km/s.

An undiscovered planet, many light-years from Earth, has one moon, which has a nearly circular periodic orbit. If the distance from the center of the moon to the surface of the planet is 2.225×105 km and the planet has a radius of 3.150×103 km and a mass of 7.90×1022 kg , how long (in days) does it take the moon to make one revolution around the planet? The gravitational constant is 6.67×10−11N·m2/kg2.
