    How much energy is required to launch a 1kg satellite 185581.1 metres above the

    earth? Gravitational constant = 6.7 x 10^ -11 Mass of Earth = 6 x 10^24 Distance to travel = 185,581.1 metres Mass of satellite = 1kg I'm guessing that the answer has to be in Joules, and I have no idea how to go about this! Thanks in advance :)
