Two spheres travelling in opposite directions collide

[QUOTE="Woolyabyss, post: 4452668, member: 426882"] I drew a diagram of the two spheres at impact like you said. using the line between the centre of the spheres and the r distance between there centres i constructed a right angled triangle.I was able to use trig to figure out the angle was 30°. for (ii) I subsituted the value of cos30 into.... v1 = (-2/√3)ucos∅ and figured out v1 = -u I Substituted this into the equation v2 = -2v1 which means v2 = 2u since the j vector is the same before and after I used Pythagoras theorem for both spheres and figured out the j vector. I then used Pythagoras theorem again and figured out there speeds after impact(the resultant vector of both the j and i components) were u√2 and u2√2 which according to the back of my book are the right answers so thanks for the help.
