The exploration is coherent and well organised, progressing logically from a simple projectile model to drag, thrust and a piecewise ascent/descent model. Relevant equations and comparisons are presented in appropriate places. The introduction does not name the mathematical area of the syllabus, the page numbers are centred at the bottom rather than in the bottom-right corner, body text is about 10 pt, the conclusion is underdeveloped, and the sign conventions are inconsistent. These prevent full marks.
