A geosynchronous equatorial orbiting (GEO) satellite orbits 22,300 miles above the equator of Earth it completes one full revolution each 24 hours.Assume Earth's radius is 3960 miles.
a)How far will the GEO satellite travel in one day?
b)What is the satellite's linear velocity in miles per hour?

Question

amistre64 · Answer

radius earth + radius above earth = R

C = 2pi R, is the lengthit travles in 24 hours

amistre64 · Answer

... distance above earth, not radius above earth .. :)

anonymous · Answer

3966+22,3=3.982.3?

amistre64 · Answer

the , is not a decimal in this application

anonymous · Answer

find diameter first ?

amistre64 · Answer

22300
+3960 
------
26260

amistre64 · Answer

diameter?  i spose if you like diameter beter than 2R

amistre64 · Answer

when we add the distance above the earth to the radius of the earth itself we get:  26260 as the overall Radius of our circle

amistre64 · Answer

the distance traveled is the circumference of the greater circle

amistre64 · Answer

and that distance divided by 24 is the speed

amistre64 · Answer

C = 2pi 26260

26260
26260
-------
52520 pi = distance traveld in miles right?

anonymous · Answer

3960 is radius of small circle or big circle?

amistre64 · Answer

small; since the earth itself is at the center of the whole thing

amistre64 · Answer

and the satellite is so much more farther up than that ... so add the 2 distances together

anonymous · Answer

than a) = 2pi26260 ?

amistre64 · Answer

yes

anonymous · Answer

b)  2pi26260/24 ?

amistre64 · Answer

yes, and simplify as wanted

anonymous · Answer

can you show me  in picture , where 22.300 miles
