Hi ppl, could someone just clarify this for me
i need to find the minimum velocity that the satellite meteosat (time period is 23h56min and altitude is 35800km + radius of earth(6370km)) must be given to escape from the force of attraction of the Earth.
I started by saying that the total energy needed to effect this is GMm/2(R) where M is mass of earth, m is mass of satellite and R is orbit. Then I equated this to mv^2/2
My final answer was 3078ms^-1 Could someone verify my working or at least show me where I made an error if there is one?
Thanks, Joe
