## Homework Statement

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 6.0x10^24 kg.

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

## Homework Equations

## The Attempt at a Solution

distance = 18x10^6 + 6.4x10^6 = 2.44x10^7

mass Earth = 6x10^24

mass satellite = 150kg

energy = (-GMm)/r = 2.46 x10^9

My answer is very wrong! Please help! Thank you :)
