Question

an artificial satellite is moving in a circular orbit of radius 42250km .calculate its speed if takes 24 hours to revolve around the earth.

Answer 1

Speed=distance/time
Speed=42250/24
Speed =1760.41666667

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!
