Jawaban:

The M4 carbine, or M4 Carbine, is a shortened, lightweight version of the M16 assault rifle. The M4 carbine has 80% of the same parts as the M16A2. The M4 has a choice of semi-automatic fire and three-round burst (same as the M16A2), while the M4A1 has a choice of semi-automatic and automatic. The M4A1 is also sometimes equipped with a heavier barrel, to withstand the heat generated from automatic firing for extended periods of time.

Bullet speeds range from about 120 m/s (390 ft/s) to 370 m/s (1200 ft/s) in musket weapons using black powder (gunpowder), to over 4,000 ft/s (1,200 m/s) on modern weapons with high-performance magazines such as the .220 Swift and .204 Ruger, finally up to 5,700 ft/s (1,700 m/s) for tank guns firing kinetic-energy penetrating ammunition. The acceleration of a projectile is highest at the muzzle, and begins to descend due to the effects of air.
