Please provide me a step by step analysis of how i would solve this problem? An ice skater is holding out a 18 kg mass in her hand and is spinning with a linear velocity of 4.0 m/s with her arms extended 0.80 meters long in relation to the center of her body. If she pulls her arm in, still holding the 18 kg mass, so that she extends her arms to 0.20 meters, what will the Velocity of the...
