Answer:
Her angular momentum does not change.
Explanation:
Conservation of angular momentum: It states that there is no change in the angular momentum when no torque outside the system is applied to the body.
In the given problem, an ice skater spins her arm outstretched. She pulls her arms in towards her body.
The angular momentum of an ice skaters remains same as the there is no external torque applied on an ice skater. The initial angular momentum and the final angular momentum of the given system are same. Therefore, the angular momentum is conserved.
Therefore, her angular momentum does not change.
You are going 94.737 km/h or 26.316 m/s
speed = distance/time
look up a speed calculator if you have more problems like this, it’ll save you time :)
