a. Find the angular velocity needed to maintain a LEO satellite at 200 miles above earth.

b. How far above Earth is a LEO with a angular velocity of 4 radians per hour?

c. Describe the angular velocity of any LEO satellite

I posted another topic, but no one replied. THX <3!

**Reiny**, Monday, November 19, 2007 at 8:29pmThe key relationship is

linear velocity = angular velocity x radius,

a) since the satellite is 200 miles above the earth, the radius would be 4160 miles.

lin. vel = ang vel. x radius

17000 = av(4160)

4.07 = av

so the angular velocity would be 4.07 radians/hour

(remember that 2pi, or 6.28 radians is one rotation, which makes this 234º per hour)

b) this seems to be the reverse question of a). Notice we got appr 4 radians per hour as the answer to the angular velocity, so the satellite would have to be about 200 miles above the earth.

Check my calculations, this seems rather odd.
