हिन्दीA bullet is fired from a gun at the speed of \( 280\text{ m s}^{-1} \) in the direction \( 30^\circ \) above the horizontal. The maximum height attained by the bullet is \( (g = 9.8\text{ m s}^{-2}, \sin 30^\circ = 0.5) \) :
Correct answer · Option 1
1000 m
Explanation
Maximum height \( H = \frac{u^2 \sin^2\theta}{2g} = \frac{(280)^2 \times (0.5)^2}{2 \times 9.8} = \frac{78400 \times 0.25}{19.6} = 1000\text{ m} \).
