A solid sphere of mass 10 kg and radius 0.5 m is rolling on a road without sliding with an regular velocity of 12 rad/s. What is the percentage of rotational kinetic energy in the total kinetic energy of the wheel?

Explanation

To solve the problem, we need to find the percentage of rotational kinetic energy in the total kinetic energy of a solid sphere that is rolling without slipping. We will follow these steps:

### Step 1: Calculate the Moment of Inertia (I)
The moment of inertia \( I \) for a solid sphere about its center of mass is given by the formula:
\[ I = \frac{2}{5} m r^2 \]
Where:
