Gun sights are adjusted to aim high to compensate for the effect of gravity, effectively making the gun accurate only for a specific range. If a gun is sighted to hit targets that are at the same height as the gun and 85 m away at the same height, how low, as a positive number in meters, will the bullet hit if aimed directly at a target 150 m away? The muzzle velocity of the bullet is 275 m/s.
To calculate the downward deviation of the bullet's projectile, we have to calculate the angle of inclination of rhe gun in first case and from this angle we can find the time to reach the target.
Then we find the horizontal distance covered by the bullet at that time.
