to make sure, is the conclusion correct, it is impossible to react because the muman reaction is 50/100 m/s while the bullet speed is 23 millisecons?

Its impossible to react

9.14=D in meters 100=human reaction m/s 9.14/100 wat should i do then?

It takes .02285 seconds to travel 30 feet, while it takes .0914 seconds for a human to respond?

ok 9.14/400=.02285 9.14/100=.0914 Still makes no sense

30 feet=9.14 meters T=V/D 400/9.14=43.76 sec 100/9.14=10.9 sec So now what?

so acceleration for bullets=d/va a=30/400 a=.075 m/s acceleration for reflex a=30/100 a=.30 .30>.075 so it is possible to dodge a bullet? That's not what I am tryin to do, I am tweakin yo.

and what would i convert it to? 30/400= .075 but what units since i can't use m/s

my teacher said it's preferred to use those equations/

yea that sounds right but i need the equation :) thx

Nerve Impulses=50-100m/s Speed of Sound= 343 m/s Speed of a bullet (handgun)= 400-475 m/s Average mass= 16-22 grams Distance=25-30 feet Bullets Dodged=18 Time= 6 seconds (approx.) I guess I am tryin to show that using one of the equations will prove that it is impossible to dodge a bullet...

http://www.physicsclassroom.com/class/1dkin/U1L6a1.gif Those are the equations, don't know which to use

Would i use like the 3 kinematic equations? because I am still confused bro i just need to know which one.

aight but WHICH equation do i use?

yea too late to switch movies as its due tmrw, but i figured out some stuff like the speed of the bullet, mass, distance and stuff but what kinematics equation would i use to prove that it is impossible to hit a bullet? and the avg. reaction time is 50-100 m/s. Thanks
