Question

Помогите пожалуйста Из Пушки массой 100кг вылетает снаряд массой 1. кг со скоростью 100м/с Определить скорость пушки после выстрела. ​

Answer 1

Дано

m1 - масса пушки - 100 кг

m2 - масса снаряда 1 кг

v1- скорость пушки x м/с

v2-скорость снаряда 100 м/с

Используя формулу закона сохранения импульса получаем

m1v1=m2v2

100*v1=1*100

v1=1 м/с

Скорость пушки будет равна 1 м/с

Answer 2

Calculation of the Cannon's Velocity

To determine the velocity of the cannon after firing a projectile, we can use the principle of conservation of momentum. According to this principle, the total momentum before the shot is equal to the total momentum after the shot.

The momentum of an object is calculated by multiplying its mass by its velocity. In this case, the momentum of the cannon before the shot is given by:

Momentum of the cannon before the shot = Mass of the cannon × Velocity of the cannon before the shot

The momentum of the projectile after the shot is given by:

Momentum of the projectile after the shot = Mass of the projectile × Velocity of the projectile after the shot

Since the total momentum before and after the shot is the same, we can equate the two equations:

Momentum of the cannon before the shot = Momentum of the projectile after the shot

Let's denote the mass of the cannon as M_cannon, the velocity of the cannon before the shot as V_cannon_before, the mass of the projectile as M_projectile, and the velocity of the projectile after the shot as V_projectile_after.

Using the given values: - Mass of the cannon (M_cannon) = 100 kg - Mass of the projectile (M_projectile) = 1 kg - Velocity of the projectile after the shot (V_projectile_after) = 100 m/s

We can rearrange the equation to solve for the velocity of the cannon before the shot (V_cannon_before):

M_cannon × V_cannon_before = M_projectile × V_projectile_after

Substituting the given values:

100 kg × V_cannon_before = 1 kg × 100 m/s

Simplifying the equation:

V_cannon_before = (1 kg × 100 m/s) / 100 kg

Calculating the value:

V_cannon_before = 1 m/s

Therefore, the velocity of the cannon before the shot is 1 m/s.

Please note that this calculation assumes an idealized scenario without considering factors such as air resistance, friction, or recoil. In reality, these factors would affect the velocity of the cannon after the shot.
