What is the kinetic energy of a 200-kg satellite as it follows a circular orbit of radius 8.0  106 m around the Earth? (Mass of Earth = 6.0  1024 kg.)
 a. 5.0  109 J
  b. 1.0  1010 J
  c. 1.5  1010 J
  d. 2.0  1010 J
  e. 2.5  109 J

Question 2

 a. GmM/(4R)
  b. GmM/R
  c. GmM/(2R)
  d. GmM/(3R)
  e. 2GmM/(5R)
