Car moving at constant speed 100km/h
No.
engineering at its best.
After crash speed is 0 so in acceleratin hahha
>has no acceleration
Uhh, dude.
But he's right.
Then explain it otherwise you're a brainlet.
Acceleration is defined as the change in speed divided by change in time. If the car has a velocity and then after the crash no velocity, then there is also a timeframe in which this has happened. Thus it has acceleration. What a shitty bait thread.
Yes. Constant velocity, no acceleration.
Right, and then it crashed, so that constant velocity changed. So it underwent an acceleration (deceleration is acceleration in a particular direction).
I literally cannot disprove this. Newton BTFO
/thread
Wow! So when the car is moving constantly at 100km/h there is zero force!
Really made me think
yeah if your car is in space
u fukin dumbo
cant get over that this frog looks like nate diaz
So you wouldn't die if you drove into the ISS at constant speed?
:-( but... how did people inside car become inmune to spring-like forces?
The speed doesn't have to be fucking 0. IT just had to change
The people are moving at a constant speed so they have no acceleration
second law:
F = ma
F = 0
Newtons third law: in the crash a force of equal magnitude and opposite direction applies to the person, which is zero so he will be fine
This is high school stuff
There is zero net force, yeah.
but if there's zero force then it will levitate
There's a ton of acceleration. Otherwise the car would continue moving at constant speed.
What speed are the moving after the crash?
Veeky Forums really is one of the dumbest board, only slightly ahead /b/
...
I would need a supercomputer to model the crash and then I would know exactly
It is levitating at height 0 ;)
You didn't need this thread to know this, you could have just looked at all the frogposting shit in the catalog.
is delta F a thing? or am i just a retard?
You mean change in force? I'm not sure.
yeah, like in op, you get btfo cus of inertia which is a change in Force
Except, you know, the force of friction on the car, and the force the car uses to counteract said friction.
but friction is what moves the car
100 km/hr =vi
0 km/hr = vf
a = (vf-vi)/t
Find t. a is clearly negative reflecting the direction of force on the passengers.
Friction moves opposite the way you're moving dumbass. You probably voted Trump lmao.
You guys are meming.
The car's engine works to maintain the speed due to friction and air drag. But that's besides the point.
If a car crashes into a completely stationary wall the wall applies a force to the car that causes the speed to go to 0. This is likely to be a force that can injure the occupants of the vehicle.
I think you're kinda pulling my leg there buddy
Yeah, so to avoid dying in a crash you just keep your foot on the pedal and go a constant speed, dumbass. DURRRRR.
t. samefag
The car continues moving at constant speed, you don't.
Or
Pole moving at constant speed doesn't impale you because no acceleration ergo no force
So will the car phase through whatever it hit?
>calling out a samefag day after fact?
Tsk tsk
While the car has no acceleration in itself (VERY doubtful), it does have a serious deceleration when coming to an halt.
Wrong
What is "there is a force exerted on the car when it crashes" fucking normie

Best thread on Veeky Forums in forever to be honest.
