Question

скорость руженой пули при вылете из ствола 500м/с.Определите кинетическую энергию пули,если масса пули 5 г.

Answer 1

Calculation of Kinetic Energy

To determine the kinetic energy of a bullet, we can use the formula:

Kinetic Energy = (1/2) * mass * velocity^2

Given that the velocity of the bullet is 500 m/s and the mass of the bullet is 5 g, we can substitute these values into the formula to calculate the kinetic energy.

Kinetic Energy = (1/2) * 0.005 kg * (500 m/s)^2

Let's calculate the value.

Kinetic Energy = (1/2) * 0.005 kg * 250000 m^2/s^2

Simplifying the equation:

Kinetic Energy = 625 Joules

Therefore, the kinetic energy of the bullet is 625 Joules when it is fired from the barrel at a velocity of 500 m/s.
