A person sitting on a rotating chair that is initially spinning at a angular velocity of 4 rad/s. Initially, the person holds a heavy ball of mass 50 kg at a distance of 0.25 m from the center of rotation. The person then stretches the arm to 0.5 m from the center of rotation. What is the new angular velocity in rad/s? Round to the nearest integer. Neglect any frictional losses or air drag and assume the center of mass of the person's body is on the axis of rotation. m

Question
A person sitting on a rotating chair that is initially spinning at a angular velocity of 4 rad/s.
Initially, the person holds a heavy ball of mass 50 kg at a distance of 0.25 m from the center of rotation. The person then stretches
the arm to 0.5 m from the center of rotation.
What is the new angular velocity in rad/s? Round to the nearest integer.
Neglect any frictional losses or air drag and assume the center of mass of the person's body is on the axis of rotation.
