Answer:
17.71 kgm²s⁻¹
Explanation:
Angular momentum is the rotational momentum , which is quite similar to linear momentum.main difference is that here we consider a rotational motion.
*The total angular momentum of a closed system remains constant.
by definition ,
angular momentum = moment of inertia (I) × angular velocity (ω)
where
ω = 2π × frequency (f) = 2π × 6
angular momentum = 0.47 × 12π = 17.71 kgm²s⁻¹
