WebMuzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, to more than 1,200 m/s (3,900 ft/s) in modern rifles with high … WebThe radar pulses continually so reflections are at random ranges for each shot, beginning at 15 to 25 yards when the bullet passes from the side into the doppler beam. Returns may be separated by a foot to 1 yard intervals depending on the velocity.

WebWell, just from the definition of acceleration, change in velocity is equal to acceleration-- negative 9.8 meters per second squared-- times time, or times change in time. We're just talking about the first half of the ball's time in the air. So our change in time is 2.5 seconds-- times 2.5 seconds. rcpch ref values
