Purely logically, the speed of the projectile is greater than the speed of the gun. And why? Let us turn to the law of conservation of momentum, which states that the momentum of the projectile is equal to the momentum of the gun. Let M is the mass of the gun, m is the mass of the projectile (M >> m), then: M * V1 = m * V2 Since M is much larger than m, then V2 is much larger than V1.
