When a sphere of moment of inertia 'I' rolls down an inclined plane then find the percentage of rotational kinetic energy of the total energy.

Explanation

To find the percentage of rotational kinetic energy of the total energy when a sphere rolls down an inclined plane, we can follow these steps:

### Step 1: Understand the Kinetic Energy Components
When a sphere rolls down an incline, it has both translational and rotational kinetic energy. The translational kinetic energy (TKE) is given by:
\[ \text{TKE} = \frac{1}{2} mv^2 \]
where \(m\) is the mass of the sphere and \(v\) is its linear velocity.
