Question1.
Eris, the largest dwarf planet known in the Solar System, has aradius R = 1200 km and an acceleration due to gravity on itssurface of magnitude g = 0.77 m/s2.
(a) Use these numbers to calculate the escape speed from thesurface of Eris.
-> 1359.4116 m/s (Correct)
(b) If an object is fired directly upward from the surface of Eriswith half of this escape speed, to what maximum height above thesurface will the object rise? (Assume that Eris has no atmosphereand negligible rotation.)
-> 300047.8296 m (Incorrect) <======= This is my actualQuestion
Question 2.
A satellite is placed between the Earth and the Moon, along astraight line that connects their centers of mass.
The satellite has an orbital period around the Earth that is thesame as that of the Moon, 27.3 days. How far away from the Earthshould this satellite be placed?
