**Michael**, Sunday, November 18, 2007 at 5:48pma. The GEO satellite's path is circular. The distance on a circular path is the circumference. C = 2 (pi) (r) = 2 (pi) (3960) = 7920pi

b. Distance = Rate * Time

Rate = Distance/Time = 7920pi / 24 hours = 330pi

I'm 100% sure on a, 90% on b.

linear velocity = angular velocity x radius

the angl vel. = 2pi/24 rad/hr

so linear vel. = 2pi/24(26260) miles/hr

= 6875 mph
