Suppose that Planet X has 5 times the radius of the Earth and and 16 times Earth's mass. What is the ratio of the escape velocity on Planet X divided by the escape velocity on Earth?

please explain the answer
4) The escape velocity on the surface of a planet is given by 2GM R where G = 6.67 x 10-11m2 kg-1 3-2 is Newton's gravitational constant, M is the mass of the planet, and R is the radius of the planet. The escape velocity is the velocity you have to thrown an object so that it does not come back down (better hit the gym!). Write v in terms of average mass density p. Recall...

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?

2. What is the escape speed from m? a planet of mass M and radius R if M-3.2x 1023 kg and R 2.4 x 100 3. Two satellites are placed in geosynchronous orbits, orbits with a period of 24 hours, where each satellite hovers over a spot on the Earth's equator. Satellite B has three times the mass of satellite A. Wh is the relationship between the magnitudes of the gravitational forces FA and FB of the Earth on the...

A spherical planet has 12 times the earth's mass and has three times the earth's radius. It orbits a star with 5 times the sun's mass with an orbital period of 7 years. If an alien spaceship weighs 180 Zorgs on the alien planet (where a Zorg is the alien unit of weight), then what is the weight of their spaceship on earth in Zorgs?

A planet has a mass of M1, a radius of R1, and a density of Q1 A second planet has a mass of M2, a radius of R2, and a density of g2. This problem will explore the relationships between the surface gravities (g1 and g2) of the planets depending on the relative sizes of their masses, radii, and densities. Assume that planet 2 has X times the mass of planet 1, or M2 - XM1. The densities of both...
