Transcribed Image Text:
A 2.0-m measuring stick of mass 0.155 kg is resting on a table. A mass of 0.500 kg is attached to the stick at a distance of 68.0 cm from the center. Both the stick and the table surface are frictionless. The stick rotates with an angular speed of 5.70 rad/s. (a) If the stick is pivoted about an axis perpendicular to the table and passing through its center, what is the angular momentum of the system? kg m²/s (b) If the stick is pivoted about an axis perpendicular to it and at the end that is furthest from the attached mass, and it rotates with the same angular speed as before, what is the angular momentum of the system? Note that the axis of rotation is now different. How will this affect the moment of inertia of the system? kg m²/s A 2.0-m measuring stick of mass 0.155 kg is resting on a table.
