Question

An ice skater is spinning at 6.00 rev/s with his moment of inertia being 0.400 kg/m2. Calculate his new moment of inertia if he reduces his rate of spin to 1.25 rev/s by extending his arms and increasing his moment of inertia.

Answer:New moment of inertia will be

Explanation:It is given initially angular velocity

Moment of inertia

Angular momentum is equal to

Now angular velocity is decreases to

As we know that angular momentum is conserved

So

So new moment of inertia will be
