Pearson Edexcel Level 3 GCE Further Mathematics Advanced PAPER 4C: Further Mechanics 2 9FM0/4C1. Three particles of masses 2m, 3m and km are placed at the points with coordinates (3a, 2a), (a, –4a)... and (–3a, 4a) respectively. The centre of mass of the three particles lies at the point with coordinates (–x, –y). (a) (i) Find –x in terms of a and k (ii) Find –y in terms of a and k (4) Given that the distance of the centre of mass of the three particles from the point (0, 0) is 1 3 a (b) find the possible values of k (2) _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _________________________________________ [Show More]
