what is the linear velocity of the satellite if it travels in a circular orbit 8000km from the earths center and takes 2 hours to make an orbit?

Question

 A satellite traveling in a circular orbit 8000km from the earth's center takes 2 hours to make an orbit. What is the linear velocity of the satellite and what is the angular velocity of the satellite?

Answer 1

Givens:

• Radius of the orbit = 8000 km
• Period of the orbit = 2 hours

 

Angular Velocity = 2pi/period = 2pi/2 = pi radians per hour.

 

Linear Velocity = angular velocity*radius = 8000*pi km/h ≅ 25,133 km/h
