It´s not the fart that kills you, it´s the smell.

What the equation, or sentence rather, is saying; It's not the fall that kills you, it's the impact.

God damn I love physics.
#23 to #4 - bigmanblue (02/17/2013) [-]
strictly speaking its saying its not the speed that kills you its the force but in laymans terms i supose you would be right
User avatar #30 to #23 - clingy (02/17/2013) [-]
it's the force, which is the change in momentum (time derivatve) so if you have a large change in momentum over a small period of time, i.e. crashing into the ground, thats what kills you.

Reminds me of the time when Spiderman killed Gwen Stacy because his web wasn't elastic enough, so the sharp change of momentum exerted a huge force on her, snapping her neck.

And Spidey had to go and blame it on Green Goblin.

How many swags do you have?
User avatar #29 to #24 - clingy (02/17/2013) [-]
5 kilograms

Wanna do my homework for me?

Haha maybe i can help :)

A Ferrari Maranello passes a ford Pinto on the 401. The Maranello is constantly accelerating at aM. The Pinto driver accelerates at a P the instant she sees the Ferrari Pass by. At the instant the two cars pass by each other, their speeds are vM, and vP, and vM>vP. At what time t=f(vm, vp, am, ap) will the pinto catch the maranello?
User avatar #21 to #20 - clingy (02/17/2013) [-]
so at first the marnello is behind the pinto, then the pinto accelerates and passes the marnello?
User avatar #22 to #21 - derkarus (02/17/2013) [-]
yep, have to find out when that happens.
User avatar #26 to #22 - clingy (02/17/2013) [-]
ok here's what i have:
since they will have travelled the same distance (x) from the time the maranello passed the pinto to when the time the pinto catches up, you can set the two equal to each other. The maranello's distance is x=(vm)t+((am)t^2)/2
The pinto's distance is x=(vp)t+((ap)t^2)/2
Set the two x's equal to each other and solve for t
I got t=2(vm-vp)/(ap-am)

Ah, thought it was something along those lines but I am always just off on one aspect of it that ***** everything up. Thanks!
User avatar #28 to #27 - clingy (02/17/2013) [-]
i hope that's right haha i haven't done kinematics like this in years :) and you're welcome
User avatar #25 to #22 - derkarus (02/17/2013) [-]
I've gathered that the pintos acceleration is larger than the Maranello, and have made a graph(v/t) with vm starting over vp and the lines crossing about half way

Understanding the post makes me a physicist?
User avatar #53 to #43 - HarvietheDinkle (02/18/2013) [-]
No, it's the people trying to show off basic physics knowledge.
User avatar #55 to #53 - thedarkestrogue (02/18/2013) [-]
^this.
User avatar #40 - Jackimole (02/17/2013) [-]
This is dumb.
"Look at me, I know what a kinematic equation is!"

What's the point?
User avatar #38 - lordbyronxiv (02/17/2013) [-]
F = dP/dt says it better.

i cant believe i actually understand this

The Vf and Vi in the first equation should both be to the power of 2...
#62 to #58 - anon (02/18/2013) [-]
No. That is the 2as equation
User avatar #63 to #62 - ArcaciaStrain (02/18/2013) [-]
Can't honestly say I'm familiar with what you mean

I don't know whats going on, I like turtles.

It's not the fall that kills you, it's the sudden stop at the end
#39 - anon (02/17/2013) [-]
that's interesting.

this is so basically, that i can assume, that you assumed that you stop immediately. so ΔT = 0 .. deviding zero... if you stop imediately, it is not basically an acceleration (ΔV/ΔT)
User avatar #33 - domitius (02/17/2013) [-]
In simple english; it's not falling that kills you, it's hitting the ******* ground that does it
User avatar #31 - theusamajunk (02/17/2013) [-]
First equation: Final velocity = initial velocity + acceleration * time

Second equation: Force = mass * (change in velocity) / time

(change in velocity/ time) = acceleration

First thing that comes to mind.

why would you do that

What's this from?

The BBC series Sherlock

Its not the change in velocity that kills you its the sudden change in momentum.

For those of you that have no understanding of physics at the moment, here's a similar and simpler statement:

"It's not the fart that kills, it's the smell."
User avatar #7 to #6 - daniboi (02/17/2013) [-]
How Swedish are you really? "It's not the speed that kills you, it's the force."
User avatar #11 to #7 - TheMather ONLINE (02/17/2013) [-]
That's a quote from Peter Solberg.
User avatar #8 to #7 - paelaer (02/17/2013) [-]
Not Swedish enough, I'd say. I'm just a polyglot living in the States.
User avatar #9 to #8 - daniboi (02/17/2013) [-]
Ahh nvm
