For a satellite to orbit Earth at a constant distance, its centripetal acceleration
must be equal to Earth’s gravitational acceleration. If a satellite is to orbit with
a constant circular radius of 9,500,000 m, what is the approximate required
velocity of the satellite? (Recall that Earth has a mass of 5.97 x 1024 kg and G
= 6.67 x 10-11 N·m2/kg?)
A. 6178 m/s
B. 6892 m/s
C. 7128 m/s
D. 6474 m/s
