A satellite of mass mS orbits the Earth (with mass mE and radius RE) with a velocity v and an altitude h. The gravitational force FG and the centripetal force FC are given by: FG =G mS·mE (RE +h)2, FC = mS ·v2 RE +h, G=const. (a) Find an equation for the kinetic energy Ekin(h) of a satellite with an altitude h. (b) Basedonthekineticenergy,howmuchliquidhydrogen(energydensity: 10 the power of 6 J/Litre)isatleast neededtobringasmall1kgsatellite in an orbit of 400 km. (Useliterature to find mE, RE, G.)
