Homework Help: Velocity of bowling ball after the collision

  1. Nov 18, 2009 #1

    I just need this explained, please.

    1. The problem statement, all variables and given/known data

    A large bowling ball of mass 6.0 kg moving with a velocity 3.0ms-1 has ahead on collision with a single pin of mass 0.50 kg.If the pin moves with a velocity of 4.0ms-1,calculate the velocity of bowling ball after the collision.

    Are you familiar with conservation of momentum?
    Momentum is mass times velocity.
    The momentum of the system before hand equal the momentum of the system after the collision.

    Try some equations with it.

    Redd is absolutelly right:

    The law of conservation of momentym states that:

    Initial Momentum=Final Momentum

    if M=mass of bowl and m=mass of pin, V=velovity of bowl and v=final velocity of pin then:

    MV=mv+Mx where: x=final velovity of bowl.

    Substitute values to get x.
    Remember about units,
    good luck.
