Question

if l is angular momentum of rotating body and he is its rotational kinetic energy then......​

Answer 1

ANSWER
For rotating body,
given that:
Moment of inertia = I
We know that,
Angular momentum L=Iω
Now,
Rotational kinetic energy =
2
(Iω
2
)
​

So, rotational kinetic energy = (
2I
L
2

​
)
Hence, (
2I
L
2

​
) is the rotational kinetic energy.
