What is the average speed of a satellite given the following information.
1) The earth's radius = 6000 km
2) The satellite is 900 km from the earth's surface
3) The satellite's orbital period: 2 hours
4) Circumference = 2pr (p = 3.14)
r earth = 6,000 km
d satellite from earth = 900.
r satellite's orbit = 6900 km
2*pi*r = circumference = distance traveled around earth.
distance/2 = speed satellite in km/hr
d/hr x (1 hr/60 m) x (1 min/60 s) = ? km/s
