thank you very much!
so does that mean I don't consider components or angles at all?
since there are two unknowns in each equation, do I simply solve for one say in the kinetic equation then substitute it back into my conservation of momentum?
and when do you consider angles? i thought...
Problem:
"A ball with the mass of .440 kg moving east (+x direction) with a speed of 3.70 m/s collides head-on with a .220 kg ball at rest. If the collision is perfectly elastic, what will be the speed and direction of each object after the collision?
Relevant equations.

thank you very much, learningphysics! you have no idea how much better that makes me feel- i have a test tomorrow in ap physics! :-) that's what i thought, i just wasn't sure and i KNOW there'll be a problem like that on the test..
Nonconservative Force Question--URGENT!
