Question

An artificial satellite is moving jn a circular orbit of radius nearly 42km. Calculate its linear velocity if it takes 24 hours to revolve around the earth.

Answer 1

Hi..

Let us assume an artificial satellite, which is moving in a circular orbit of radius 42km covers a distance ‘s’ as it revolve around earth with speed ‘v’ in given time ‘t’ of 24 hours.= 42
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

= 150.2 km/s


Hope this helps u!!
