A gun mounted on the ground fires bullets in all directions with same speed

Question

A gun mounted on the ground fires bullets in all directions with same speed. The farthest distance the bullets could reach is 6.4 m. The speed of the bullets from the gun is ______ m/s. (Take g = 10 ${m/s}^{2}$ ) [2026]

$R_{\max} = \frac{u^{2}}{g}$

$\Rightarrow u^{2} = R_{\max} \times g = 6.4 \times 10 = \frac{64}{10} \times 10$

$\Rightarrow u = \sqrt{64} = 8 m/s$
