[QUOTE="MatusVeselka, post: 6042691, member: 649714"] [h2]Homework Statement [/h2] Hello I am trying to predict vector after collision of 2 ball in biliard. I am using angle-free representation formulas from wikipedia : [URL]https://wikimedia.org/api/rest_v1/media/math/render/svg/14d5feb68844edae9e31c9cb4a2197ee922e409c[/URL]x1 and x2 are positions of balls, m1 and m2 are masses of balls, v1 and v2 are vectors of direction before collision and the angle brackets indicate the [URL='https://en.wikipedia.org/wiki/Inner_product']inner product[/URL] (or [URL='https://en.wikipedia.org/wiki/Dot_product']dot product[/URL]) of two vectors. my values are : x1 = (0.5 , 0) x2 = (0 , 1) m1,m2 = 1 v1 = (0.5, 1) v2 = (0, 0) [ATTACH=full]229480[/ATTACH] [h2]Homework Equations[/h2] [ATTACH=full]229481[/ATTACH] [h2]The Attempt at a Solution[/h2] [ATTACH=full]229493[/ATTACH] [/B] And here its my solution with vector (0.835 , 0.329), but this result can't be correct can somebody help me what I am doing wrong ? My result is total wrong and i don't know why [/QUOTE]
