    Is Velocity Conserved in an Elastic Collision Between Two Cars?

    https://www.khanacademy.org/science/physics/linear-momentum/elastic-and-inelastic-collisions/v/how-to-use-the-shortcut-for-solving-elastic-collisions I just watched this, here he says that V1 initial + V1 final = V2 initial + V2 final for elastic collisions. Isn't this contrary to what...

    Is Velocity Conserved in an Elastic Collision Between Two Cars?

    Thanks for the reply! I've been thinking about it for the last 30 mins or so, and I think I have a simpler explanation (at least for me). Please let me know if my thinking is correct. So, the reason velocity isn't conserved is because if the cars have different masses, the velocity is...

    Is Velocity Conserved in an Elastic Collision Between Two Cars?

    My question is, in an explosion, where 2 cars at rest are pushed apart by a spring between them, is velocity conserved? Does the total velocity for both cars before spring release equal the total velocity after release? Why or why not?
