Question

a satellite that is moving in a circular orbit of radius 42250 km. calculaate its speed if it takes 24 hours to revolve around the earth

Answer 1

Speed=distance/time
So,.
Speed=42250/24
So speed=approx 1760km/hr

Answer 2

Hey there!

Given,

Radius (r) = 42250 km

Time (t) = 24 hours

Distance will equal to perimeter of the orbit

= 2πr

= 2π * 42250

Speed of artificial satelite  

= 2π * 42250/24

= 11059 km/h

Hope It Helps You!
