Explanation:
It s given that,
Mass of a planet, 
Radius of a planet, 
(1) We need to find the acceleration due to gravity for a person on the surface of the planet. Its formula is given by :



(2) The escape velocity is given by :


v = 7324.61 m/s
Hence, this is the required solution.
In order to change the frictional force between two solid surfaces, it can be changed by shorter distances and by the amount of weight it has or the amount of force that is pushing that object to go however distance it can.
