Lucky thing that guy didnt have an heavy machine gun... The 7.62 rounds of an m60 would make minced meat outta anything...
If fired from close range it does not have the capability to break the glass as the bullet does not have enough time to gain enough velocity to penetrate through the glass.
Yeah, the bullet reaches maximum velocity at the end of the barrel. It starts losing velocity the moment it leaves the barrel.
looks like the robber didn't do his 'homework'... gee that was so funny! the clerk should call all her colleagues and laugh at the robber in front of him
first of all, if he had an m60, i dont think hed be robbing banks secondly, i must clarify things as a physics nerd... the bullet will reach maximum velocity inside the barrel right after the powder explodes and horizontal velocity will remain practically unchanged throughout the duration of the bullet's flight. The only force that could affect this velocity would be air resistance, but in a short distance (for instance.. a bank lobby) this effect would be negligible....
Oh, I thought the bullet accelerates up the barrel and reaches maximum velocity at the muzzle? Isn't that the reason why barrel length (as well as amount of propellant) determines the velocity of the bullet?
