Answer:
In all type of collisions, momentum of the system always remains constant. In perfectly inelastic collision, particles stick together and move with a common velocity.
Let this velocity is . Then, initial momentum of system = final momentum of system
or m ( 2 v)
=
Initial kinetic energy
Final kinetic energy
