Explanation The initial angular speed is 10.0 rad / s , initial inertia of the skater is 2.50 kg ⋅ m 2 and final inertia of the skater is 1.60 kg ⋅ m 2 . According the conservation of angular momentum , the initial angular momentum would be equal to the final angular momentum. Write the expression for the conservation of angular momentum. I ω = I ′ ω ′ Here, I is the initial moment of inertia, ω is the initial angular momentum, I ′ is the final moment of inertia and ω ′ is the final angular momentum. Substitute 10.0 rad / s for ω , 2.50 kg ⋅ m 2 for I and 1.60 kg ⋅ m 2 for I ′ in the above equation to calculate ω ′
