# An artificial sat

Answer :

We know that, (i)
As the Satellite is moving in a circular orbit ∴ the Distance = Circumference of the Orbit
We know that Circumference= 2πr (ii)
where r= radius o

π= (It is a constant)
According to Question

Radius, r = 42250 km

Putting the value of r in (ii)
We get Circumference= = 265571.42 km

Putting these values in (i), we get

Speed, v= speed = 11065.4 km/h

= km s-1

= 3.07 km s-1
