Question
Describe how an artificial satellite using a two-stage rocket is launched in an orbit around the Earth.

Solution
- Launching of a satellite in an orbit around the Earth cannot take place by the use of a single-stage rocket. It requires a minimum of two stage rocket.
- With the help of the first stage of the rocket, satellite can be taken to the desired height above the surface of the Earth.
- Then the launcher is rotated in a horizontal direction i.e., through 90° using the remote control and the first stage of the rocket is detached.
- With the help of the second stage of the rocket, a specific horizontal velocity (vh) is given to the satellite so that it can revolve in a circular path around the Earth.
- The satellite follows different paths depending upon the horizontal velocity provided to it.
