QUESTION:
Two satellites are in circular orbits around a planet that has radius 9.00 × 106 m. One satellite has mass 68.0 kg, orbital radius 5.00 × 107 m, and orbital speed 4800 m/s. The second satellite has mass 84.0 kg and orbital radius 3.00 × 107 m. What is the orbital speed of this second satellite?
ANSWER:Step 1: Orbital radius of first satellite r = 5.00 x 10 m 1 Orbital radius of second satellite r = 3.00 x 10 m7 2 Mass of first satellite m1= 68.0 kg Mass of second satellite m 284.0 kg Orbital speed of first satellite 1 = 4800 m/s
