A large number of bullets are fired in all directions with the same speed v. What is the maximum area on the ground on which these bullets will spread ?

• A

  $\frac{{\mathrm{\pi v}}^2}{\mathrm{g}}$

• B

  $\frac{{\mathrm{\pi v}}^4}{{\mathrm{g}}^2}$

• C

  ${\mathrm{\pi }}^2\frac{{\mathrm{v}}^2}{{\mathrm{g}}^2}$

• D

  $\frac{{\mathrm{\pi }}^2{\mathrm{v}}^4}{{\mathrm{g}}^2}$
