a figure skater is spinning slowly with arms outstretched. she brings her arms in close to her body and her moment of inertia decreases by 1/2. by what factor does her rotational kinetic energy change?

1) you move around throw out the entire time 2) 25
3) a ralley
4) a long sleeve tight shirt with spandex shorts
5) kinda a squat with ur arms in front of you it’s used so you can easily move behind the ball and your arms can easier switch from a pass to a set
6) throw the ball in the air and hit with ur good hand
7) throw it slightly and hit it with your fist
8) idk this one but probably like an attack (some people call it a spike)
9) when someone on the opposing team attacks the ball you can block it, so it goes back on the other teams side

explanation: i play volleyball lol
