to do a physics problem for real life D: how high would a 170lbs person have to fall to exert 300 lbs of force

this could win me like half a million dollars for serious

I feel like I should be able to answer this.
Mason says
16 years ago
Ah, fuck it. I don't remember a thing about physics.
Mason says

WAIT! WAIT! WAIT! MY SISTER'S BOYFRIEND WAS A PHYSICS MAJOR! JER, I'VE GOT YOUR BACK!
Jeremy says
16 years ago
haha man if you could figure that out i will buy you lunch
Jeremy says
16 years ago
i keep getting hung up on the momentum equation cuz i get left over second units that should cancel out somewhere
Mason says
16 years ago
Yeah. I can't stand him, but the dude's a damn genius. When he logs on facebook I'll hit him up

Lunch?

Ill do it
Mason says

Sam. We can't buy you lunch. YOU LIVE IN THE MIDDLE OF BUMFUCK NOWHERE.
Jeremy says

hahaha i found out why i cant figure out the answer and it turns out you have to factor in how long the force is being applied
Jeremy says
16 years ago
but i dont know how long the force is being applied because he doesnt bounce back up
Mason says
16 years ago
Hey. Here's a new idea. Let's just drop a couple 170 lb people. Get a PSI measuring device. You've got the rest figured out I think.

hahaha i might just do yahoo questions :-P
Jeremy says

i need to find out how high my dad would have to fall from to exert 300 lbs of pressure to prove that he could not have exceeded the 300 lb
Jeremy says
16 years ago
weight limit on the treestand he fell out of by bouncing on it
Jeremy says
16 years ago
because if its more than 3 inches it would be impossible
Jeremy says
16 years ago
and we're sueing the company that made the treestand because it broke and he fell and broke his back
Jeremy says
16 years ago
aw man, i tried it with one second of force application and got 14 meters. thats not true at all

i would help, but i don't have physics until school starts D:

let's test it out!!

everytime we fail, we'll know what NOT to do

this sucks, mason already said this, i didn't read the conversation above
nikolias

fuck it, i'm getting out a physics book, hold on.
nikolias
16 years ago
FUCK, i gave the book to this kid i know and he hasn't give it back
nikolias

i feel bad because i should know this stuff D:

I FOUND MY PHYSICS CHART!!!!

i'm trying to figure out what formula to use to solve this problem. i'm rusty :-(
nikolias
16 years ago
:/ all i could figure out so far is that your dad's mass is 77110.3, and i'm not even sure if that is right
Jeremy says
16 years ago
i got the formulas all boiled down now, and i need the length of impact time to figure it out :-(
nikolias
16 years ago
77110.3 gr.
Jeremy says
16 years ago
haha no thats right, its around 77kg which is what i was using, thats in grams
urbankodama says

i was going to give you people the answer (barring wind resistance) but no one here deserves it
Jeremy says
16 years ago
thats a more discriptive explanation of what i need, i asked yahoo pplz a question
nikolias
16 years ago
i'm not exactly the best at physics, haha, haven't had the class yet, but i've been studying over the summer, haha
nikolias
16 years ago
ahh i see! impulse and momentum
nikolias
16 years ago
force multiplied by time is impulse, and mass multiplied by velocity is momentum
nikolias
16 years ago
i think
Jeremy says
16 years ago
when i looked up momentum i found the units for momentum to be NxS newtons times seconds, and newtons is a unit of force
Jeremy says
16 years ago
so i used force times seconds in place of momentum, is impulse different? its been 2 years since i had physics
nikolias
16 years ago
i have a new hatred for physics
nikolias
16 years ago
this is hard ;_;
Jeremy says
16 years ago
haha impulse is a change in momentum so thats not what im doing, i could use that to find the force perhaps if i could find initial momentum
nikolias
16 years ago
i really am stumped on this, and have no idea how to continue this formula
nikolias
16 years ago
wish i could help :-( hope you get your answer! i'll try asking my dad in the morning, he's good with physics
Jeremy says
16 years ago
haha nah i have all the physics down and know how to do it now im just missing that one number, l impact time, which you cant figure out
