Beware! Your 'or' worries me...

There is a big difference between kinetic energy and momentum.

In elastic collisions there is conservation of kinetic energy. (this is what I was fishing for - didn't want to just give it away)
In all collisions there is conservation of momentum.

Now, do you have a battle plan to conclude this exercise ?

thank you Sir for your patience and help.
