JEE Main2026Apr 4, Shift 2Physics

Q.

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 $g = 10 m/s^{2}$ )

Your answer

Solution

Maximum range for projectile motion (at 45°) is $R_{ma x} = \frac{v ^{2}}{g}$ .

$6.4 = \frac{v ^{2}}{10} \Rightarrow v^{2} = 64 \Rightarrow v = 8 m/s$ .
