Question

A gun is firing bullets with velocity $v_0$ at the same angle with horizontal by rotating throught ${360}^{\circ }$ in the horizontal plane. the maximum area covered by the bullets is :

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

For maximum range, $\theta ={45}^{\circ }\Rightarrow R_{max}=\frac{v_0^2}{g}$
$\therefore$ Maximum area $=\pi \left(R_{max}^2\right)$
$=\frac{\pi v_0^2}{g}$
