An ice skater has a moment of inertia of 25 kgm2 when his

An ice skater has a moment of inertia of 2.5 kg*m2 when his arms are outstretched and a moment of inertia of 1.0 kg*m2 when his arms are tucked in close to his chest. If he starts to spin at an angular speed of 2.0 rps (revolutions per second) with his arms outstretched, what will his angular speed be when they are tucked in?
