Angular Momentum?

Question

A particle of mass 0.450 kg is attached to the 100 cm mark of a meter stick of mass 0.200 kg. The meter stick rotates on a horizontal, frictionless table with an angular speed of 4.00 rad/s.

(a) Calculate the angular momentum of the system when the stick is pivoted about an axis perpendicular to the table through the 70.0 cm mark.

Answer 1

i*omega =M*R^2*Angular velocity
