A bullet weighing 25 gm fired from a G3 Infantry Assault Rifle achieves muzzle velocity of 800 m/s.
To calculate the kinetic energy of the bullet, we can use the equation:
Kinetic Energy (KE) = (1/2) * mass * velocity^2
Before we proceed, it's important to ensure that the units for mass and velocity are consistent. Currently, the mass of the bullet is given in grams (gm), so we need to convert it to kilograms (kg).
Given:
Mass of bullet = 25 gm = 0.025 kg
Muzzle velocity = 800 m/s
Now, plugging these values into the equation:
KE = (1/2) * 0.025 kg * (800 m/s)^2
Simplifying further:
KE = 0.5 * 0.025 kg * 640000 m^2/s^2
KE = 8000 J (joules)
Therefore, the kinetic energy of the bullet fired from the G3 Infantry Assault Rifle is 8000 joules.
