Homework Help: Intertial Mass

  1. Nov 26, 2009 #1
    Moment of Inertia

    A particle of mass 0.400 kg is attached to the 100-cm mark of a meter stick of mass 0.100 kg. The meter stick rotates on a horizontal, frictionless table with an angular speed of 4.00 rad/s. Calculate the angular momentum of the system when the stick is pivoted about an axis (a) perpendicular to the table through the 50.0-cm mark and (b) perpendicular to the table through the 0-cm mark.

    What is the moment of intertia of the particle at the end of the meter stick? I know how to find the moment of intertia of the meter stick.
