Two cars of equal mass collide inelastically and stick together after the collision. before the collision, their speeds are v1 and v2. what is the speed of the two-car system after the collision?

Thank you for posting your question here at .  The total mass and total velocity of the system is conserved if two cars of equal mass collide inelastically and stick together after the collision. before the collision, their speeds are v1 and v2.

I hope the answer help.
