Question

The mass of a spaceship is 1000kg. It is to be launched from the earths surface out into free space. The value of g and r (radius of earth) are 10m/s and 6400km respectively. The required energy for this work will b

Answer 1

Hey Mate

This is clearly a question of the topic of Gravitation where we study about escape velocity and gravitational force.

since the spaceship has to be launched you need to first find the escape velocity required for the spaceship of the given mass to go into the space.

after finding the escape velocity it'll be used to find the energy using 1/2mv² where v will be the escape velocity you found and m will be the given mass of the spacecraft.
