Question

An artificial satelite is moving in a circular orbit of radius 42250km . calculate its speed if its takes 24 hours to resolve around the earth

Answer 1

radius of the circular orbit, r=42250 km
therefore, circumference of the circular orbit=2πr = 2×22/7×42250km
therefore, speed =distance covered/time taken
=2×22/7×42250/24
=11065.476km/h
therefore the speed of the satellite =11065.476km/h
hope it helps u

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!
