SUMMARY
The discussion centers on calculating the recoil speed of a gun when a bullet is fired, specifically using the conservation of linear momentum principle. A bullet with a mass of 0.40 kg is fired at an initial velocity of 400 m/s from a gun weighing 5.0 kg. The correct approach involves applying the equation m1v1 = m2v2, where m1 is the bullet's mass and velocity, and m2 is the gun's mass and recoil velocity. This method allows for the determination of the gun's recoil speed accurately.
