Inelastic collision between 2 objects

  1. Oct 14, 2009 #1
    1. The problem statement, all variables and given/known data
    2 objects of equal mass collide inelastically having initial speed v.
    after that they move off together with speed v/3.
    what is the angel between the initial directions?



    2. Relevant equations



    3. The attempt at a solution
    mv = 2m v/3 cos ....

    Try doing it for just one of the objects:

    mv = m(v/3)cos(theta)

    Hi wing_88! :smile:
    hmm :redface:

    start again, and be systematic …

    first, say in words what your conservation equation is …

    then write it out, and you won't make mistakes. :wink:
