What is the final velocity of two objects after a perfectly inelastic collision?

• m1v1,i + m2v2,i = m1v1,f + m2v2,f

• m1v1,i + m2v2,i = (m1 + m2)vf

• m1v1i+m2v2i=m1 v1f+m2v2f

• 0=m1v1+m2v2

What is the difference between conservation of momentum and conservation of kinetic energy in perfectly inelastic and elastic collisions?
