Question

an artificial satellite is moving in cicular orbit of radius 42250km. Calculate it's speed if it takes 24 hours to revolve around Earth ​

Answer 1

Answer:

3072.5 m/s

Explanation: V =$\frac{2\pi r}{T}$

=$\frac{2*\pi*(42250 x 1000)m}{24 * 60 * 60s}$

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!
