m1v1+m2v2 = (m1+m2)v3
I know that it has something to do with the conservation of momentum, but I'm not sure exactly what.
I know this one:
m1v1i+m2v2i+=m1v1f+m2v2f
But what's that first one?
Thanks!

this is the case of PERFECTLY INELASTIC collission..
in this case the two bodies after collission move together... so their velocity is same and the total mass is the sum of the two masses...

Conservation of momentum is correct. This is the equation used when the two masses collide inelastically; that is, they stick together after the collision. The first two terms are the individual momenta before the collision; the right-hand side is the momentum of the system ( that is, m1 and m2 stuck together) after the collision.
