Homework Help: Colliding Balls

  1. Nov 7, 2008 #1
    1. The problem statement, all variables and given/known data

    There are two balls travelling and they collide. How do there momentum change.
    What is the impulse done to ball B by ball A.

    2. Relevant equations

    delta momentum = 0
    impulse = ?

    3. The attempt at a solution

    the first part

    i think its C

    becuz A is moving up and B is moving down
    the horizontal movement didnt change

    and so the impulse from ball A to ball B
    must be pointing DOWN right?

    and the answer must be B ??

    right?

    Hi soupastupid! :smile:
    Right! :biggrin:

    (btw, impulse and change-of-momentum are the same thing :wink:)
