## Homework Statement

-- This is out of Rendezvous With Rama by Arthur C. Clarke

You know it is 907184 kg and is going 50,000 m/s

So how much energy does it have right before it hits the earth?

## Homework Equations

Do I use Fg= Gm1m2/r^2 ?

Ek=1/2mv^2?

I have ΔE=1/2mv^2 written down as an equation to use as well.

## The Attempt at a Solution

I think I'm supposed to calculate the potential energy at 2 different spots and find the ΔE, but I'm not sure.

E=Gm1m2/r+1/2mv^2 would that work?
