Very mathematical ! Add in some physics .
Write two equations : COM and COk.e
Fast track to : u1-u2 = v2-v1 (dont worry about its mass)
Sub into COM (wiser choice that COk.e)
Then solve it, to find uknowns.
Important to take note of directions given, unknown must assume positive value (unless specified already)
