Distance from planet = 10^14 meters, Radious of the planet = 10^7 meters, mass of the object = 100kg
g on the planet's surface = 10 m/s^2, g 10^14 meters away from the planets center = 2.5 m/s^2
The Attempt at a Solution
I calculated the speed of the object at the surface of the planet ( 8931.5 m/s ) using Energy Conservation. I trןed to calculate the time using r(t), r(a) graphs.
