A satellite has-recently been placed in a nearly circular orbit
2000 kilometers above the earth’s surface. Given that the
radius of the earth is approximately 6400 kilometers and that
the satellite completes its orbit in 12 hours, calculate the speed
of the satellite in kilometers per hour.
C = 3.14*DIA = 3.14(2*6400) = 40,192km.
V = d/t = 40192km / 12hrs = 3349.3km/hr
