A spaceship is stationed on Mars. How much energy must be expended on the spaceship to launch it out of the solar system ? Mass of the space ship = 1000 kg, mass of the sun =` 2 xx 10^(30) `kg , mass of mars = `6.4 xx 10^(23) `kg, radius of mars = 3395 Km: radius of the orbit of mars = `2.28 xx 10^(8) ` km , G = 6.67 `xx 10^(-11) N m^(2) kg^(-2)`.

Explanation

`3 xx 10^(11)` J
