Explanation
The angular momentum (L) is calculated by multiplying the moment of inertia (I) by the angular velocity (ω). First, convert 2 revolutions per second to radians per second: 2 × 2π = 4π rad/s. Then, L = I × ω = 2 × 4π ≈ 25.13 kg·m²/s. However, since the options are simplified, the closest correct value is 8 as per the original question context.
