A5000-kg spacecraft is in a circular orbit 2000 km above the surface of mars. how much work must the spacecraft engines perform to move the spacecraft to a circular orbit that is 4000 km above the surface? assume the mars radius is 3.4 \times 10^6 m3.4×10 6 m and the mass of mars is 6.4 \times 10^{23}6.4×10 23 kg. (express your answer in the format: 1.23 \times 10^{10} j1.23×10 10 j as "1.23e10 j".)
