TOP TIP: Root three in this Further Pure 2 exam betrays presence of 30 or 60 degree angles in this complex numbers question. All maths students should know exact values of 30, 45 and 60 degree angles – they come up so much. See my exam bucket http://jped.co.uk/ExamBucket/exambucket.php, for this FP2 2014 and many others.
Edexcel’s January 2013 Mechanics 2 exam paper has massively intricate last part of last question to determine existence of third collision. Examiner’s report says not many candidates supplied an answer, which is not a surprise. This, and much more, is freely available on my exam bucket website: http://jped.co.uk/ExamBucket/exambucket.php.
