It’s all about intersections, intersections of vectors. If you fire while swinging and follow through does the path of the projectile only acquires the tangential velocity at the end of the barrel or does the projectiles lateral velocity increase with distance from the muzzle? If so could you swing the gun fast enough to shoot around a corner.
Just thinking which is what shooters do.
“If so could you swing the gun fast enough to shoot around a corner.”
Nope.
The lateral velocity would decrease as no more lateral energy is imparted to the bullet once it leaves the barrel. Perhaps that lateral velocity would carry the bullet “around the corner” but some miles away from the corner itself.
