Question
A bullet fired at an angle of with the horizontal hits the ground 3 km away. By adjusting its angle of projection, one can hope to hit a target 5 km away. Assume the muzzle speed to be same and the air resistance is negligible
- possible to hit a target 5 km away
- not possible to hit a target 5 km away
- prediction is not possible
- None of the above
The correct answer is: not possible to hit a target 5 km away
The body covers a horizontal distance AB during its flight. This horizontal range is given by
Hence, maximum range with velocity of projection cannot be more than 3.464 m, Hence, it is not possible to hit a target 5 km away.
