Bullet Prolem

[leolaw]

Why does the bullet fire at an angle would hit the ground before the one fire straight up?

 

[PowerMacG5]

Can you rephrase your question, it doesn't make great sense. (What degree angle, positive or negative, etc...)

Air resistance

Nah. Most HS or intro physics classes don't talk about air resistance. They prefer the ideal case.

A bullet fired straight up will always hit the ground later than a bullet fired at any other angle. A bullet does not produce lift.

Thats the only way that the one at an angle would hit the ground first.. With no air resistance they'll hit at the same time.

That's what I would have said, but his english looks like Wduaqnug's.

Nope, they won't hit at the same time. The vertical components would be different. The one shot at an angle would have a vertical component of v*sin(theta), while the one shot up will have a component of v.

This is why I can't do good in physics 🙁

Nope, they won't hit at the same time. The horizontal components would be different. The one shot at an angle would have a horizontal component of v*sin(theta), while the one shot up will have a component of v.

By horizontal you mean vertical I hope. 😀

Yeah, sorry. Long night. Math was still right though 😛.

Wdanqnug?

because the bullet fired at an angle has a smaller vertical component than the one fired straight up, assuming the exit speeds are the same.

What about in Engrish? 😀


j/k

Yes, but the one fired at an angle will hit the ground first, even with air resistance. There is no way that the bullet fired at an angle could hit the ground after the one fired straight up unless the one fired at an angle produced lift, which bullet's do not (not common one's at least).

that's what i said 🙂 well... what is implied anyway. intuitively something that has a lower upward speed would hit the ground faster.

Or english.

DOH!
Aftermath beat me to it.

This thread just reminded me of something. When we were kids and had snowball fights I'd always lob one high in the air. As they were looking for that one to fall I'd drill them with a line drive.

Reminds me of the snow ball cannon in a Calvin & Hobbes strip where Calvin pegs his dad 😛
