Question

Из ружья массой 3 кг производят выстрел. Пуля массой 10 г вылетает из ствола со скоростью 200 м/с. Определите скорость отдачи ружья.

Answer 1

тоже по закону импульса

mV=m2V1+m2V2=-m1v1+m2V2

начальная скорость ружья нуль

mV=m2V2

V=0.01*200/3=0.66

Answer 2

Calculating Recoil Velocity of the Gun

To calculate the recoil velocity of the gun, we can use the principle of conservation of momentum. The formula for the recoil velocity of the gun can be expressed as:

Recoil Velocity of the Gun = (Mass of the Bullet * Velocity of the Bullet) / Mass of the Gun

Given: - Mass of the gun (m1) = 3 kg - Mass of the bullet (m2) = 10 g = 0.01 kg - Velocity of the bullet (v2) = 200 m/s

Using the conservation of momentum, we can calculate the recoil velocity of the gun.

Calculation

Recoil Velocity of the Gun = (0.01 kg * 200 m/s) / 3 kg

Recoil Velocity of the Gun = (0.01 * 200) / 3

Recoil Velocity of the Gun ≈ 0.67 m/s

So, the recoil velocity of the gun is approximately 0.67 m/s.
