B Calculate minimum work to launch rocket into orbit

  1. Jan 7, 2017 #1
    Scientists are planning to launch a rocket from the surface of the Earth into an orbit at a distance of 18000 km above the centre of the Earth. The radius of the Earth is 6400 km and it has mass 6.0 x10^24 kg.

    What is the minimum work done to move the 150kg mass of the rocket into this orbit?

    Thank you! :)
