Understand the momentum and velocit

  1. Feb 8, 2007 #1
    Hi guys, i don't understand the momentum and velocity and when they say elasticity in the following question...

    What will happen when equally massive carts collide elastically with one another at equal velocity?

    What will happen when the collision is inelastic?

    I am very confused. please help me.

    It means "What will happen if two carts with equal mass and same magnitude of velocity ( obviously in opposite direction!) collide elastically? What will happen when the collision is inelastic?"

    An elastic collision is one in which there is no loss in the kinetic energy of the system, i.e. sum of kinetic energies of carts before collision = sum of kinetic energies of carts after collision.
