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 −1
