    In a perfectly inelastic collision, the two particles colliding stick together after the collision: http://en.wikipedia.org/wiki/Inelastic_collision#Perfectly_inelastic_collision

    would two moving cars that run into each other and stick and are still moving be inelastic?

    Yes, as per the graphic in the wikipedia article.

    u see i throw mud at the wall the mud sticks on the wall hw is momentum conserved in this collision?

    would it be perfectly inelastic?

    Momentum is conserved. It's just the the mass of the object being hit--the wall, the building, the earth on which the earth is built--is so very large that you don't observe it moving in response the the mud. Yes, it would be perfectly inelastic.

    my worksheet says that it cant be perfectly inelastic

    Which scenario: the cars or the mud?

    u mean that m is very large so v is negligible??

    It says why cant perfectly inelastic be shown on this website http://www.walter-fendt.de/ph14e/collision.htm

    If the two cars collide and after the collision stick together and have the same velocity, then even by the link you've just given, the collision is perfectly inelastic: "After a perfectly inelastic collision, however, both bodies have the same velocity; the sum of their kinetic energies is reduced, compared with the initial value, because a part of it has changed into internal energy (warming up)."

    Heres the question: In class we learned that there are 3 kinds of collisions: Elastic, Inelastic, and Perfectly Inelastic. Which types were demonstrated here? Why was the third type not able to be demonstrated with this website?

    Inelastic and Elastic were shown on there

    That java plug in is not working for me, so I can't answer "Why was [perfectly inelastic] not able to be demonstrated?" as I can't see what it's doing or what inputs it is asking for.

    Brent. After looking at your website, I observe that elastic and perfectly inelastic are being shown. Perfectly inelastic collisions means the object stick together. Imperfect inelastic collions do not stick together, yet kinetic energy is destroyed, unlike in elastic collisions where kinetic energy is conserved.
