Question

an artificial satellite is moving in a circular orbit of radius 42250km. Calculate it's speed of it takes 24 hr 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

Here is ur answer...

Answer 2

Answer:

3.07 km/s^-1

Step-by-step explanation:

Distance covered by the satellite in 24 hours

s=2πr

=2×3.14×42250=265464.58 km

Therefore speed of satellite,

v = distance travelled/time taken

=265464.58/24×60×60

=3.07 km/s^-1
