If the rotational kinetic energy of a body is increased by 300 %, then determine percentage increase in its angular momentum.

Explanation

To solve the problem of determining the percentage increase in angular momentum when the rotational kinetic energy of a body is increased by 300%, we can follow these steps:

### Step 1: Understand the relationship between rotational kinetic energy and angular momentum
The rotational kinetic energy (K) of a rotating body is given by the formula:
\[ K = \frac{1}{2} I \omega^2 \]
where \( I \) is the moment of inertia and \( \omega \) is the angular velocity. The angular momentum (L) is given by:
\[ L = I \omega \]
