Find the magnitude of the centripetal acceleration of a particle on the tip of a blade, ` 0 .30 ` metre in diameter, rotating at `1200` revolution per minute.

Explanation

To find the magnitude of the centripetal acceleration of a particle on the tip of a blade, we will follow these steps:

### Step 1: Find the radius of the blade
The diameter of the blade is given as 0.30 meters. The radius \( R \) can be calculated using the formula:
\[ R = \frac{\text{Diameter}}{2} \]
Substituting the given diameter:
