Speed of rocket in interstellar space is
Explanation:
Given that,
A rocket is fired with a velocity V = near the earths surface and goes upwards
Let us consider ,v be the speed of rocket in interstellar space.
In interstellar space, gravitational potential energy is zero
Applying conservation of energy at surface and interstellar space:
We know that
=
=
=
Thus, speed of rocket in interstellar space is
