A hypothetical planet has a mass 3 times that of the Earth and a radius twice that of the Earth. Calculate the value for acceleration due to gravity near the surface of this hypothetical planet.
A hypothetical planet has a radius 1.2 times that of Earth, but has the same mass. 1.)What is the acceleration due to gravity near its surface? Express your answer to two significant figures and include the appropriate units.
The radius of a planet is three times that of Earth and its mass is nine times that of Esrth. The acceleration due to gravity on this planet is
A hypothetical planet has 3 times the mass of Earth and twice the radius of the Earth. What is the surface gravity on this planet? r = Rplanet g = GMplanet / r2
Planet X has 20 times the mass of the earth and 3 times the earth's radius. It orbits star Y at a distance of 8 AU, where 1 AU is the earth-sun distance. Star Y has twice the mass of our sun. (a) What is the orbital period of Planet X in years? (b) An astronaut has an earth weight of 120 lbs. What is her weight on the surface of planet X?
The acceleration due to gravity on the surface of a planet is nine times as large as it is on the surface of Earth. The mass density of the planet is known to be seven times that of Earth. What is the radius of this planet in terms of Earth's radius? RE Rplanet t

Ratio of the mass of mars to the mass of earth is 0.107 and the ratio of the radius of mars to that of earth is 0.532. Use these ratios with the known value of the acceleration due to gravity on the surface of the earth, calculate the acceleration due to gravity on the surface of mars. What will be the weight of a human weighing 637 N on earth on mars? What will be his mass on mars? [5...
