Homework Help: Physics: Collison/Momentum Problem

Posted by Cicilia on Wednesday, January 25, 2012 at 8:03pm.

A 15 kg mass, moving east at 5 m/s, collides elastically with another 10 kg mass, moving west at 1 m/s. After the collision, the larger mass moves off with a velocity of 3 m/s. What is the final velocity of the smaller mass?

Is it 4m/s? Or would it be 2m/s?
Do you add the momentum of the 2 masses because of conservation of momentum or subtract them because they're going in different directions?
