Correct Answer: Negative
Solution : The Correct Answer is- Negative
Kinetic and potential energy are negative when added together. This is because the missile is restrained by the earth's gravitational field at speeds below escape velocity. As a result, it has negative total energy. The minimum velocity needed for an object to escape a planet's or another celestial body's gravitational pull is known as the escape velocity.
