Momentum transfer

    The blue ball is a gear actually, with 2 racks on both its side which are attached to 2 masses each (M1 = M2).

    If momentum is made to gain in the arrangement from the side M2...it will also impart momentum to M1.

    Suppose all this happens in a body to which the whole arrangement is attached.

    And this motion is stopped by colliding M1 to this body itself.

    Will this body gain momentum (if its light)?

    Assume the body to be heavier than M1+M2

    as long as the body is not rigidly attached to the system given in the picture, it will move.

    Same opinion with me...actually that can't happen cause momentum has been imparted...M1 and M2 cannot be rigidly attached.

    So motion has to be transferred.

    Thanks for confirming.
