As an ice skater begins to spin, his angular speed is 3.04 rad/s. After pulling his arms, her moment of inertia is reduced to about ¾ the original moment of inertia. What is the angular speed after pulling his arms?

Step 1
The conservation of angular momentum states that the initial angular momentum of a system is equal to the final angular momentum of the system. In this case, the ice skater is the system, and we can assume that there are no external torques acting on Show more…
