What will be the speed of an artificial satellite moving in a circular orbit of radius 43000
km, which takes 24 hours to revolve around the earth?
Solution
Radius of the orbit = 43000 km = 43000 x 1000 m
Time taken for one revolution = 24 hours = 24 x 60 x 60 sec
Speed = ?
Speed = distance/time = 2πr/ time = ( 2 x 3.14 x 43000 x 1000) / (24x60x60) = 3125.46 meter per second. or 3.1 kilometer per second.
