Question

REPUBLIC
The spacecraft to travel to the outer space, must have
A) nimum velocity of 22.4 km/s
B) maximum velocity of 11.2 km/s
(C) minimum velocity of 11.2 km's
maximum velocity of
22.4 km/s..​

Answer 1

Explanation:

(C)minimum velocity of 11.2 Km/s i.e. escape velocity.

you can find escape velocity by formula (2gR)^1/2

where R--->radius of earth.

and,g---->acceleration due to gravity on earth.

and you can define maximum velocity because minimum velocity which is required to throw a spaceship from orbit of a planet is escape velocity for that planet and you can throw either at escape velocity or greater than escape velocity for throwing a spaceship from orbit of a planet.

Answer 2

Answer:

minimum velocity of 11.2 km's
