Answer :
Final answer:
In the event of a hang fire with a muzzleloader, keep the gun pointed safely and wait a minute before opening the action. An ordinary rifle recoils due to Newton's third law, while recoilless rifles allow gases to escape backwards to reduce recoil. When aiming at long-range targets, adjustments are made for gravity, and higher muzzle velocities can reduce bullet drop.
Explanation:
If you are shooting a muzzleloader and a hang fire occurs, it is important to keep the gun pointed in a safe direction and wait a minute before opening the action. This safety procedure allows any delayed ignition to happen without risk of injury. Opening the action or trying to fire again immediately could be dangerous, and it is also not advisable to stand close behind the muzzle of a recoilless rifle, even though it is designed to minimize recoil.
An ordinary rifle recoils (kicks backward) when fired due to Newton's third law of motion, which states that for every action there is an equal and opposite reaction. Since the bullet is propelled forward with a certain force, the rifle is pushed back with an equal force. The barrel of a recoilless rifle is open at both ends to allow gases to escape backwards, reducing the recoil experienced by the shooter.
Gun sights are adjusted high to compensate for gravity, ensuring accuracy at a certain range. If a gun is sighted for 100.0 m and used to shoot a target 150.0 m away without adjusting the aim, the bullet will hit lower than intended. Larger muzzle velocity would reduce the bullet's drop over a distance due to a shorter travel time, while air resistance would slow the bullet and increase the amount of drop.
