0-50mph in 600 ft
how many seconds is this?
- fyoucher10
4.4 seconds

Holy fuck - that's quicker than the Kessel Run.
- You mean in 5 parsecs?TheBlueOne
- Pfft, fuckin Correllian ships.harlequino

wrong site

Can't be done with this info. We do not know the accelration time of the vehicle. Could be 0-50 in 30 seconds, could be 30 minutes. The only information we have is 600 feet.
- Thats what I thoughtiheartfun
- not exactly. he is telling you the acceleration. at the end of 600 feet he's gotten to 50mph7point34
- there's an equation here, i just don't know what it is7point34
- he hasn't told you the acceleration, just the final speed. Could have taken weeks.ribit
- Who said anything about a 'vehicle'?NotByHand

I say yes.

... you have been served.

You know nothing about the time. All you know is that a vehicle accelrated from 0-50mph by the time it reached 600 feet. Could be a ferrari, could be a 1947 Buick. Don't know that,

You can't calculate it on these figures alone. It could half an hour, or two seconds... or a week.
- ^
HahahahahOrbit - ofcourse you can calculate it. if you take 50mphdigdre
- but does it accelrate 0-50 over 5 seconds, or 30 seconds? How do you figure that?harlequino
- just take a constant of 50mph, jesus.digdre
- ^
< hahahahahaha >harlequino - But it's NOT constant. It's progressive.harlequino
- take a Renault megane then! ffs!digdre
- why?ribit

So the equation is Time=Distance/Rate....
- ribit0
You can't just assume the car accelerates at a constant rate. No car does, and the problem doesn't state that you can assume constant acceleration.

you're saying it could take a week to get to 50 miles per hour, but it's not as if it idled for 590 feet and then shot to 50mph. it's got to be moving the entire time at an increasing speed and it has to reach 50mph before reaching 600 feet traveled.
i could be and probably am completely wrong, but i'm assuming there is an equation here that i just don't happen to know
- for instance once you get to 20 miles an hour how long would think it would take to go 600 feet? 2 seconds maybe?7point34
- this fucker is fast, can we agree to that?7point34
- Not necessarily.harlequino
- josh has lost the plot.Jnr_Madison
- probably more than that but you get the idea i'm getting at
7point34 - i just shit the chest7point34
- Silly, but: You could have an ant that reaches 50mph, but its acceleration is like a sine wave, peaks toward the end.harlequino

We are missing a piece of info. we need to know one of the following:
A. The vehicle's normal accelration is Xmph/Ysecondor
B. The vehicle took reached 600 feet in distance in X time.
- If we are talking vehicles you needs a bunch of perfomance data, acceleration varies over time.ribit
- iheartfun0
EXACTLY SO IT CAN NOT BE DONE WITH THE GIVEN INFORMATION!
- cornficker can7point34
- True! Conficker can do anything!iheartfun
- He'll put a cob through this bitch!harlequino
- 7point340
so where's jester? i need to know the answer!
and he must show all work

Actually we all started assuming its a car. If the question refers to a ball running on a straight incline... then you probably could solve it? (constant acceleration, ignoring surface and air drag).
- Sure, IF the speed is a constant, no problem.harlequino
- speed doesn't have to be constant, just acceleration.ribit
- of course we could also start the ball running at a constant speed, and that makes it even easier!ribit
- oh wait no it's 0-50.. so we have to deal with acceleration.. dang.ribit
- Yeah I suppose, since gravity, drag, all that jazz is the same. It's different above becasue it's (assumed) to be a car.harlequino
