Question

A bullet accelerates the length of the barrel of a gun 0.750 m long with
a magnitude of 5.35 x109 m/s. With what speed does the bullet exit the
barrel?​

Answer 1

Answer:

Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots or shell) with respect to[1] the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle).[2] Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets,[3] to more than 1,200 m/s (3,900 ft/s)[4] in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to 1,700 m/s (5,600 ft/s)[5] for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to 8,500 m/s (28,000 ft/s).
