Question 2

A satellite is in a circular parking orbit 6.98  106 m from the center of Earth. To initiate a Hohmann transfer, a rocket gives it an accelerating thrust so that its speed is increased to 8300 m/s.
 
  How far from the center of Earth will the satellite be when it reaches its apogee? The mass of Earth is 5.97  1024 kg and G = 6.67 x 10-11 Nm2/kg2. A) 3.12  107 m
  B) 2.48  107 m
  C) 1.06  107 m
  D) 6.73  107 m
  E) 4.75  107 m
