Answer:
5. 9GmM/(10R)
Explanation:
m is the mass of the satellite
M is the mass of the earth
W is the energy required to launch the satellite
Energy at earth surface = Potential energy (PE) + W
W = Energy at earth surface - Potential energy (PE)
But PE =
Therefore: W = Energy at earth surface -
Energy at earth surface (E) at an altitude of 5R =
But
Therefore:
W = E - PE
