A particle of mass 0.450 kg is attached to the 100-cm mark of a meter stick of mass 0.125 kg. The meter stick rotates on a frictionless, horizontal table with an angular speed of 2.00 rad/s. (a) Calculate the angular momentum of the system when the stick is pivoted about an axis perpendicular to the table through the 50.0-cm mark. kg · m2/s (b) Calculate the angular momentum of the system when the stick is pivoted about an axis perpendicular to the table through the 0-cm mark. kg · m2/s
