Question

Calculate the angular momentum ( in kg* m^ 2 /s) of an ice skater spinning at 6.00rev / s given his moment of Inertia is 0.470 kg * m ^ 2

Answer 1

17.71 kgm²s⁻¹

Step-by-step 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
