Answer:
I don't know about these problems at all.
Explanation:
I don't know about physics at all
The angular momentum of an object is equal to the product of its moment of inertia and angular velocity.
L = Iω
I = 1/2 MR²
I = 1/2 x 13 x (0.2)
I = 1.3
ω = 2π/t
ω = 2π/0.3
ω = 20.9
L = 1.3 x 20.9
= 27.2 kgm²/s
8.0 m/s if there is no air resistance. (B)
Less if there IS any air resistance.
