Question
Hello, I need help in how to get the solution for question 7. Please and thank you.
With her arms up over her head, a 55.0-kg figure skater has a rotational inertia of 0.649 kg m². As she brings her arms extended outward, her rotational inertia changes to 1.515 kg m². If she was rotating once every 0.884 seconds with her arms overhead, what is her new rotational period with her arms extended? | (a) 2.33 s (b) 2.06 s (c) 0.493 s (d) 0.379 s 6. How much work did the figure skater in the previous question do in reconfiguring her limbs? (a) -102 J (b) -51.0 J (c) -9.37 J (d) 0.00 J 7. (e) 9.37 J (f) 51.0 J (g) 102 J
