The maximum range of a rifle bullet on the horizontal ground is `6 km`. Find its maximum range on an inclined of `30^@`.

Explanation

To solve the problem of finding the maximum range of a rifle bullet on an inclined plane of \(30^\circ\), given that its maximum range on horizontal ground is \(6 \, \text{km}\), we can follow these steps:

### Step 1: Understand the maximum range on horizontal ground
The maximum range \(R\) on horizontal ground is given by the formula:
\[ R = \frac{u^2}{g} \]
where \(u\) is the initial velocity of the bullet and \(g\) is the acceleration due to gravity. We know from the problem that \(R = 6 \, \text{km}\).
