Question

Plz Write full answer : 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

Answer:

Distance covered by the satellite in 24 hours

s=2πr

  =2×3.14×42250=265464.58 km

Therefore speed of satellite,

v=  

time taken

distance travelled

​  

=  

24×60×60

265464.58

​  

=3.07 km s

Answer 2

Explanation:

let us assume an artificial satellite which is moving In a circular orbit of 42250km covers a distance of s as it revolve around the earth with speed v given time t of 24 hours =42250hm

time taken by artificial satellite =24h

distance covered = circumference of circular orbit

speed v = 3.073kms
