    In a perfectly elastic collisons, we always add the speeds if objects are travelling in OPPOSITE directions and subtract when they are in SAME direction. It's the opposite of the usual rule plus KE has to be conserved in elastic collisons. And for this question : Intial momemtum= 2mu+(-mu) = mu...
