Question

Learning to shoot a rifle involves using the cocking mechanism and trigger to load and fire a bullet. It also involves knowing how to overcome a recoil while hitting a target. As one practices the skill and becomes more proficient, one performs all these movements without

a) Conscious thought
b) Physical effort
c) Inhibition
d) Advanced technology

Answer 1

When a rifle is fired, the bullet is propelled forward and the rifle experiences a recoil due to the conservation of momentum. It is generally not safe to stand close behind a recoilless rifle.

Step-by-step explanation:

When a rifle is fired, the bullet is propelled forward with a certain amount of force. According to Newton's third law of motion, every action has an equal and opposite reaction. Therefore, the rifle experiences a recoil, or a backward kick, as a result of the bullet being propelled forward. This recoil is due to the conservation of momentum in the system.

As for standing close behind a recoilless rifle, it is generally not safe to do so. While the barrel of a recoilless rifle is open at both ends, the force exerted by the escaping gases still creates a significant backward force, which could cause injury or damage if standing directly behind the rifle.
