Question

A satellite completes one revolution of a planet in almost exactly one hour. at the end of one hour, the satellite has traveled 2.0 × 107 meters and is only 10 meters away from its starting point. what is the numerical value of the satellite's average velocity after that one hour? a. -3.77 × 10–2 meters/second b. -2.77 × 10–3 meters/second c. -2.62 × 10–2 meters/second d. -5.55 × 103 meters/second

Answer 1

V = (S2 - S1) / 3600 average velocity of satellite

V = 10 m / 3600 sec = 2.78E-3 m/s

(b) is the correct answer
