The 9mm benchmark was our reference S&W Model 39 semiautomatic pistol. work done = 2500 J. Mark came the closest in his answer, but I want to address some of the deviations from idealism in greater detail. Solved Bullets from two revolvers are fired with the same - Chegg At the Dallas Crime Lab we were constantlytesting new ammunition for law enforcement. @Bill Slugg For most guns there is going to be kick back and human error in steadily holding it level. It looked like we had an answer. Since the time to fall scales with $\sqrt{\frac{2h}{g}}$, a change of 2 parts in 300 in gravity results in the bullet falling more slowly by about 1 part in 300. 3.00) m/s, and a 3.00-kg particle has a velocity (1.00 + 6.00) m/s. The bullet from gun #1 is twice as heavy as the bullet from gun #2. A "magnum" load has slightly more powder and more pellets, so that the muzzle velocities are not greatly increased, but the total kinetic energy is greater because of the greater mass of pellets. Learn the difference between revolvers and semi-auto pistols and what makes them different. The trajectory marked "Drag" shows how much longer it takes for the bullet to drop when it has horizontal velocity: this is the effect of quadratic drag, and results in the fired bullet taking significantly longer to drop. The guy on top is correct. The convenient simplification that arises is: $$|\vec{V_b}(t)| = (V_{bx}^2 + V_{by}^2)^{\frac{1}{2}} \approx V_{by}(t)$$. Such measures include shape modifications like round (round nose), flattened (wadcutter), or cupped (hollowpoint) bullet nose. The ratio of the momentum imparted to gun #1 to that imparted to gun #2 is: A) 2:3B) 3:2 C) 2:1 D) 3:1 E) 6:1 Ans: C Difficulty: M C ) 2:1 Question: D Question 3 2 pts Bullets from two revolvers are fired with the same velocity. Do you feel lighter/heavier when you're on a train than when you're not? Full choke gives a 15 inch spread at 20 yards, while no choke gives a 30 inch spread at the same distance. The Model 1917 had a half-inch barrel advantage over the Government Model but also had typically loose World War I military service tolerances, including a barrel/cylinder gap crowding 0.009 inch. This ultra-high-speed photo shows a bullet being fired out of a Smith and Wesson revolver. (Wilson, 1978) A rifled slug fired from a shotgun may have a range up to 800 yards. JavaScript is disabled. So the differences for the 21/2 difference in barrel length were 136 fps, 144 fps and 153 fps . A circuit contains resistors of 8resistance and 4resistancewhat is combined resistance if the resistors are combined: Ammunition Choices for 9mm Revolvers | Active Response Training
