Organic test is complete combustion or incomplete combustion producing CO2 and CO only. Or reacts with air to decompose. Can be confirmed by mass spectroscopy.

The question said to ignore orbital velocity and rotational of the moon. And over the 500km altitude the acceleration change would be to large to be a projecitle motion question. So the kinetic energy which was equal to the work done could be derived from part i). 1.26x10^7= 1/2mv^2 hence...

Whoa what an interesting and challenging test that challenges us in unique and reasonable ways. (Insert multiple choice and graph question) NESA - "Hahahaha lets make the cut-off 90' For velocity, did anyone get 1122ms?
