Why is the upper bound of e not equal to 1 in this case?

Might be missing something, but I can't see any justfitication for it not being equal to one.

Thanks another question I have is what they they mean by momentum exchanged, I've found the impulse of particle A and B which both equals 192mu/25

It's nothing esoteric.

Impulse equals change in momentum, and one gains it whilst the other loses it, hence they exchange some momentum, equal to the impulse.

Note: Both impulse and momentum are vector quantities, hence, being strictly accurate, we need to talk about magnitude of same here.

I thought so thanks, both impulses were positive which didn't make sense I must have made a mistake somewhere
