When a falling meteor is at a distance above the Earth's surface of 1.2 times the Earth's radius, what is its acceleration due to the Earth's gravity?

You are visiting a newly discovered exoplanet (mass M and radius R) that completes one rotation about its axis every 12 hours (Earth hours). You place your spaceship in a geostationary orbit at an altitude h = 6R above the planet's surface. While in orbit you decided to beam down to the planet to investigate the surface. While on the surface you perform a simple kinematics experiment and discover that the gravitational acceleration at the surface is ap = 0.60g, where g is the gravitational acceleration on the Earth's surface. You can assume that the exoplanet is a uniform sphere, and that your spaceship's orbit is circular. Note: A geostationary orbit is a special type of geosynchronous orbit where the satellite/spaceship remains at the same position above the equator throughout its orbit. Technically the prefix "geo" indicates the Earth, but we'll go ahead and use the term here in reference to this new planet. (a) What is the radius of the planet? R = km (b) What is the mass of the…

A 44.0 kg satellite has a circular orbit with a period of 3.30 h and a radius of 3.80 × 106 m around a planet of unknown mass. If the magnitude of the gravitational acceleration on the surface of the planet is 2.00 m/s2, what is the radius of the planet?

A satellite orbits earth at a distance of 670km above the surface of the earth. The radius of the earth is RE=6357km. The mass of the earth is ME = 5.97 × 1024 kg. The gravitational constant is 10-11 Nm² G = 6.67 × kg² Determine the speed of the satellite (in km). hr

1) What is the speed of the satellite in m/s?

At a particular instant the magnitude of the gravitational force on a moon due to the planet it orbits is 6.73×1022 N. The mass of the moon is 8.9×1022 kg and the mass of the planet is 2.0×1027 kg. What is the distance between the center of the planet and the center of the moon? (a) 5.14 × 1013 m(b) 1.77 × 1017 m(c) 1.41 × 103 m(d) 9.41 × 106 m(e) 4.21 × 108 m
