1. An 8000 kg satellite is launched from the surface of the Earth into outer space. What initial speed is needed by the satellite in order to reach a great (i.e., infinite) distance from the Earth, neglecting the effects of air resistance in the atmosphere? (G = 6.67 × 10−11 N·m2/kg2, ME = 5.97 × 1024 kg, RE = 6.37 × 106 m.)

  • A)9,200 m/s.

  • B)18,900 m/s.

  • C)11,180 m/s.

  • D)25,200 m/s.

  • E)8,450 m/s.
