A particle of mass 0.350 kg is attached to the 100 cm mark of a meter stick of mass 0.150 kg. The meter stick rotates on a horizontal, frictionless 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 60.0 cm mark.(b) What is the angular momentum when the stick is pivoted about an axis perpendicular to the table through the 0 cm mark?
