You Math Smart? Problem -- Two Guns

[fistfullofsteel]

don't we have to include gravity into the equation?

 

[Troll]

Well, I have a problem with the 'both guns fire bullets at the same velocity'. That is bullshit. The longer the muzzle, the faster the bullet

First mistake of novice students. Reread the problem.

gravity

Gravity would have the same effect on both bullets, thus, it can be ignored.

I read the problem, did you read my answer? Reality is that the longer the muzzle, the faster the bullet. This problem was simplified for math students to derive an answer. I never said that gravity affects one over the other. I said the bullet from the gun with the longer muzzle would, in reality, travel faster.

The question clearly stated that both bullets are traveling at the same speed, and everyone knows that the shorter the distance, the shorter the time taken to cover that distance given all things equal

Yes, BPB, that is what I was trying to say... and I'll say it again:

"The one from the left hand gun

1.5" < 6.25"

assuming that the both bullets travel at the same rate of speed..... all other info is just B.S."

May, you are an idiot. Shut up!

Dude, it doesn't say anything about the length of the muzzle on the freaking guns.
Damn it, that's what I mean. READ IT. It describes the distance the muzzle is away from his head!!!

The left-hand gun muzzle is 1.5" (3.8 cm) from his left temple. The right-hand gun muzzle is 6.25" from his right temple.

READ IT. IT DOESN'T SAY THEY ARE TOUCHING HIS HEAD, WHICH WOULD IMPLY ONE WAS LONGER THAN THE OTHER!

Well, I have a problem with the 'both guns fire bullets at the same velocity'. That is bullshit. The longer the muzzle, the faster the bullet. That is why rifles are able to cause more damage. A bullet from a .22 pistol better be inches from the target, otherwise it will only piss the dude off. A .22 from a rifle however will do some damage.

I'd rather be shot with a .45 then with a .22. The .45 will just go through you, but the .22 is going to bounce around inside you.

Only if they are traveling the same distance

WRONG Only if they are the different heights from the ground
gravity of the earth, if the guy is on earth, pulls downward. Toward the center of mass of the earth. We are indeed only concerned with the horizontal component of velocity of the bullets.
The only thing gravity will do in this case is make one hit him in the ear hole and the other in the earlobe.
