What is the initial angular momentum of the system? Express your asnwer in kilogram-meters squared per second. On an old-fashioned rotating piano stool, a woman sits holding a pair of dumbbells at a distance of 0.650 m from the axis of DA AEQ rotation of the stool. She is given an angular velocity of 3.35 rad/s , after which she pulls the dumbbells in until they are only 0.180 m distant from the axis. The woman's moment of L= kg . m /s in the direction of the motion inertia about the axis of rotation is 4.85 kg . m and may be considered constant. Each dumbbell has a mass of 4.55 kg and may be considered a point mass. Neglect friction.
