an observer is located an unknown distance away from a cannon. a cannonball is fired from the cannon at 425m/s. the speed of sound is 345 m/s. if the cannon ball goes past the observer 0.2 seconds before the sound is heard, how far away is the cannon?
Thanks guis :D

:sigh:
Take 345 times the page number
Schoolpunch.
If you can't be asked to it, why should we?
You don't ever state that you're having trouble, or anything. Just "here guyz do this kthx"
Facepunch is not your homework answers.
so in other words, u guys cant do it? k cool
In other words you're a lazy bastard?

If optimistic won't answer for you, obviously no one else will.

no i cant do it...

no wii kant do ur simpel mats
Try coming to us with humilty instead of asshattery.

It will do a better job than we will.

Okay fine, it's 3.5 miles away, happy now?
Well uh, bit dazed right now, but just looking at the question, and not really trying to solve it. The cannon is 1.2x faster than the speed of sound. And since it's heard .2s after, wouldn't it just be 345m away?
lol how am i being an asshat? i would say admiting i cant do it is showing slight humility...
Sounds like basic Kinematics to me.
close thread before somebody gives him the answer

also, this isn't yahoo answers

lol idiot. kinematics, like its name implys, deals with forces and energies of objects moving. you guys are worse than 4chan

You're an asshat since you ask internet to do your homework for you.
I just did the calculations out.
100 feet
You're welcome.
Still going to stay with my guess, 345m.
Of course OP can't do it. He can't even tell the difference between dynamics and kinematics.
You can solve this with a graph. y=424x and y=345x where x is time in seconds. Then when they are .2 away in the x direction then y value where that happens should be the distance. This may not be the right answer but I can't be bothered to think it out in depth.
That is if this takes place in a perfect world with no friction or energy loss

:golfclap:
also facepunch is not your personal homework assistant
It's 4.2 cm.
Like your dick.
More like 155.25 meters. I am not explaining how to do it, but there is your answer. I hope you fail your test. For the record this problem was really easy, you should learn it.

Ok. If we're worse you can leave.
The correct answer is 28.4 km
