Question

Рассчитать время движения пули в стволе автомата Калашникого, если его скорость 715м/с, а ускорение = 616м/с

Answer 1

а=(V-Vo)/t; Vo=0; a=V/t; t=V/a=715/616=1,16 c - это ответ.

Answer 2

Calculation of Bullet Travel Time in the AK-47 Rifle

To calculate the time it takes for a bullet to travel through the barrel of an AK-47 rifle, we need to know the bullet's velocity and the acceleration it experiences.

Given: - Bullet velocity: 715 m/s - Acceleration: 616 m/s²

To calculate the time, we can use the equation of motion:

v = u + at

Where: - v is the final velocity - u is the initial velocity - a is the acceleration - t is the time

In this case, the bullet starts from rest (u = 0) and reaches a final velocity of 715 m/s (v = 715 m/s). The acceleration is 616 m/s².

Substituting the values into the equation, we have:

715 = 0 + 616t

Simplifying the equation, we find:

t = 715 / 616

Calculating this, we find that the time it takes for the bullet to travel through the barrel of the AK-47 rifle is approximately 1.16 seconds.

Please note that this calculation assumes a constant acceleration throughout the bullet's travel in the barrel. In reality, the acceleration may vary due to various factors, such as the bullet's interaction with the rifling inside the barrel. Additionally, this calculation does not take into account other factors that may affect the bullet's travel time, such as air resistance.
