Question

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

Answer 1

Explanation:

An artificial satellite is launched into a circular orbit around the Earth with velocity v relative to the reference frame moving translationally and fixed to the Earth's rotation axis. ... In an earth's orbit, centripetal force is equal to gravitational pull of the earth.

An artificial satellite is launched by a launch vehicle consisting of a multistage rocket of at least two stages. The satellite is mounted in a capsule atop the launch vehicle.

A rocket is a reaction engine whose basic driving principle is Newton's third law of motion. Hot gases of the burning fuel mix leave the rocket at very high speed in the downward direction. The reaction of this ejecting gas propels the satellite and the launch vehicle vertically up.

When a two-stage rocket is used, the first- stage is used to provide a high initial thrust straight up which gets the satellite through the thickest part of the atmosphere to the desired altitude.

The empty first-stage is detached and the remaining launch vehicle is rotated through 90°. Then, a controlled and lower thrust by the second-stage imparts the correct horizontal velocity, called the critical velocity, to the lite to put it into a stable circular orbit. This velocity is deter Y is determined by the altitude of the satellite
