A figure skater has a moment of inertia of 87 kg*m2 with her arms extended outwards. She has a rotational velocity of 1.93 rad/s. She then draws her arms inwards giving her a new moment of inertia of 65 kg*m2. What is her new angular velocity? rad/s.

How much work must she do to draw her arms inwards?

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.
