A certain planet has an escape speed V. If another planet of the same size has twice the mass as the first planet, its escape speed will be
escape velocity V = (2GM/R)^1/2
M2 = 2M , R2 = R
V2 = (2GM2/R2)^1/2 = (2GM/R)^1/2 * (2)^1/2 = 1.414 V

The escape speed from Planet X is 20000 m/s . Planet Y has the same radius as Planet X but is twice as dense. What is the escape speed from Planet Y?
The escape speed from Planet X is 14000 m/s. Planet Y has the sameradius as Planet X but is twice as dense. What is the escape speed from Planet Y?
A satellite having orbital speed Vorbits a planet of mass M. If the planet had same but double its average mass density, the orbital speed of the satellite at the same distance from the center would be OV. V/2. OVE. O 2V. Ow2.
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...
What is the escape speed from a planet with mass M-4.28x10 kg and radius R-5.45x10 m2
Find the escape speed from a planet with a mass of 3×10^24 kg and a diameter of 2×10^6 m. Use 2⁄3×10^-10 N·m2/kg2 for the gravitational constant.
The escape speed from a distant planet is 45 km/s. If the acceleration of gravity on the planet surface is 14.0 m/s2, what is the radius of the planet?
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...
Two planets have the same surface gravity, but planet B has twice the mass of planet A. If planet A has radius r, what is the radius of planet B? A) B)r C) We were unable to transcribe this image
The escape velocity of a bullet from the surface of planet Y is 1759.0 m/s. CALCULATE the escape velocity from the surface of the planet X if the mass of planet X is 1.59 times that of Y, and its radius is 0.895 times the radius of Y.
