A spaceship is stationed on Wlars. 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 x 10^8`kg, `G= 6.67 xx 10^-11 m^2kg-^2`.
