Momentum is always conserved in collisions, meaning that the total momentum of the objects AFTER the collision is the same as the total amount of momentum of the objects BEFORE the collision. Therefore, the answer is ...

Well done. That's why, when analysing collisions, we always use conservation of momentum.
