Determine what kinetic energy will be possessed by the bullet fired from the gun. Its speed at departure is 600m / s, and its weight is 7.5g.
Given: V (velocity of the considered bullet when leaving the gun) = 600 m / s; m (bullet mass) = 7.5 g (7.5 * 10 ^ -3 kg).
The kinetic energy that the considered bullet will possess can be calculated by the formula: Ek = 0.5 * m * V ^ 2.
Calculation: Ek = 0.5 * 7.5 * 10 ^ -3 * 600 ^ 2 = 1350 J (1.35 kJ).
Answer: The bullet at the moment of its release from the gun has a kinetic energy of 1.35 kJ.
