Question

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

Hey mate,

Speed = distance / time

= 42250/24

= 1760 km /h

Answer 2

Answer:

11065.47 km/hr

Explanation:

Distance traveled in one revolution= circumference

                                                          = 2$\pi$r

                                                          = 2*22/7*42250

                                                          = 1859000/7

Time= 24 hours

Speed= d/t

          = 1859000/7*24

          = 232375/21

          = 11065.47 km/h

∴ Its speed is 11065.47 km/h.
