Collision Conservation of momentum

  1. Nov 18, 2008 #1
    1. The problem statement, all variables and given/known data
    If two objects one travelling right and the other travelling left collide. The collision is inelastic.
    What would the sign of the instantaneous velocity of each object?


    2. Relevant equations



    3. The attempt at a solution
    I think the instaneous velocity would be zero for both the objects at the point of collision but iam not sure.

    It depends on the velocity of the objects and their masses. If both m's and v's are equal, then it would stop.

    You may be talking about the act of them combining, where you would have to look at the impulses of them both. Impulse=Ft=change in momentum. From there, you can find force, acceleration, etc. and find the speeds at certain points in the collision, I believe.
