I dont know if conservation has momentum...but momentum is certainly conserved!
Momentum before collision=momentum after collision
and...
momentum(p)=mass(m)*velocity(v) -

It might be worth looking at some Mechanics 2 (A-Level Maths) papers because they have quite a few questions on momentum and impulse.

For questions concerning the principle of conservation of momentum, take one direction as positive. Work out the total momentum in that direction before the interaction , then work out the total momentum in the other direction and minus this from the original value.
Now you can substitute and solve to find any single value for after the interaction. Usually, they give you all the data except one value and you have to work that out. From there it's just some simple algebra. -

Good! Momentum's easy as long as you remember to take into consideration the direction of the particles (etc) and can do scale drawings. -
