Question

An artificial satellite is moving in a circular orbit of radius 42250 km. calculate its speed if it takes 24 hours to revolve around the earth.

Answer 1

 Let us assume an artificial satellite, which is moving in a circular orbit of radius 42250 km covers a distance ‘s’ as it revolve around earth with speed ‘v’ in given time ‘t’ of 24 hours.= 42250

Radius of circular orbit r

Time taken by artificial satellite t=24 hours

Distance covered by satellite s =Circumference of circular orbit

 Speed of satellite v

= 3.073 km/s

Answer 2

Let the satellite moving in circular orbit of radius be 42250km

Radius of circular orbit “r”

Time taken by artificial satellite t=24hr

Distance covered by satellites s=circumstances of circular orbit

Speed of satellite “V”

=3.073km/s
