Question:

How many miles per hour would a spacecraft need to reach in order to pull away from the Sun's gravity?

Rules:

Unlimited amount of guesses are permitted.

ACW will monitor the thread and reply if your answer is TOO HIGH or TOO LOW

Blog owners, good luck! :thumbsup

24000 mph?

Bump! :thumbsup

TOO LOW :)

the space craft can go as slow as .01 mph as long as its self propelled and can maintain that speed. escape gravity only applies if you are going to run out of fuel and need to be travelling at X km/h to achieve orbit.

BUT according to quantum physics, everything in the universe exerts a gravitational pull on every other thing in the universe - it just gets really really small when you get far away. but it's still there.

So assuming the question really is "What is the escape velocity of a space shuttle from the sun's gravitational field from Earth's orbit, ignoring Earth's gravitational field"

Then it's (6.67E-11 * 2E6 * 2E30 )/1.5E11

=1.78E15 m/s

also 617.5 km/s escapes velocity - that's only to outbalance the pull from the sun, not to completely escape its effects, technically you'd never be able to travel to a place where you couldn't measure any pull from the sun's mass, if you had good enough measuring equipment

I mean, gravity is weak as shit, compared to other forces. If you have enough fuel to propel the craft at any positive velocity, you will EVENTUALLY get away from the gravitational pull of the sun.

617.5 km/s

mmmm, wrong answer! :)

Btw, the velocity must be expressed in mph, not km/h, not m/s, not any other.

Too low, from now on pls post only in mph.

Thx.

Really? Now I definitely want to know the right answer...

if the question was about pulling away from the sun and not pulling away from the sun's gravity, which you can't ever fully avoid the influence of... Mph is a velocity so you are escaping the suns gravity no matter what so it would be 1/x as x goes to infinity basically you could go infinitely slow and still be moving away from the sun because mph is a velocity.

or maybe i am dumb or maybe i am not looking at this in the right LIGHT (get it, the sun = light)

1 409 269.86 mph

Too High.

Visit our new page ACW! :thumbsup

Ok one last try, btw i don't even want the posts i'm more interested in the answer:

http://www.google.com/search?hl=en&s...ur&btnG=Search

1 381 940.25 miles per hour

here is an exact one based on numbers from Google

V = Sqrt(2GM/R)

Where G is the gravitational constant - 0.00000000006673
M is the mass of the sun - 1.98892 × 10^30 kg
Radius of the sun - 695 500 000 metres

zingle dingle give the calculator a whirl and you get

1 381 940.25 mph

:1orglaugh:1orglaugh

I think this is the right one, I did the same thing before but I just rounded a few numbers.

Also, impressive use of Google!!

Guys, you are aiming way way too high.
BTW, it's miles per hour (mph), just in case someone think it's meters or whatever.

:1orglaugh:1orglaugh
Aiming way too high?

That's the answer dude, looks like writing isn't the only thing you guys fail at! :1orglaugh:1orglaugh

617.5 km/s was too low, and now we're aiming way too high when the two are pretty much the same speed!

Can you clear it up a bit or what man lol it kills me that you say it's not the right answer because I must get the right answer :(

Can you just post the answer and reasoning behind it so I can sleep tonight. :(

And if you dare say the speed of light I will go crazy for so many reasons lol.

They have good writers. Why would you say that?

Due to an ongoing writer war!

:ak47::BangBang::BangBang:

I don't know though, that was months ago when I last heard about them so maybe they've learned a few things in the mean time.

Edit: One of those things wasn't math, or question writing, one or the other!!

27000mph to be exact

Come on, I write my own blog posts just give me the answer and randomly give out the prize!! :)

Too low....

300000 miles per hour

too high...

Your answer is wrong or the question you're asking is wrong.

617.5 km/s was too low, and that's more than 300000 mph which you said was too high.

Which one is it, too high or too low? Or do you even know? Like I said you're either asking the wrong question or you yourself have the wrong answer.

Escaping from the gravitational pull of a spherical object such as a planet, moon or star is represented by V = Sqrt(2GM/R).

And we've used that to give you answers, but you say they're wrong and then go on to be ignorant of the FACT that you don't have your numbers straight.

FACT: You said 617.5 km/s was too low.
FACT: You said 300,000 mph was too high.

FACT: 617.5 km/s = 1 381 308.16 mph.

FACT: 1 381 308.16 mph > (is greater than) 300,000 mph.

So how can 617.5 km/s be too low when something less than it is too high?

Chelo your number sense is horrible, if you still don't understand the concept of one number being bigger than another then how can you even try to begin to understand the concept of escape velocities?

I'm lost... can I get a hug?

We're still giving away 15 Free Blog Posts to whoever guesses the right asnwer.

Hint: The answer is somewhere between 60,000 and 120,000 mph

Hey there Captain, how u doin' :D?

a hug? mmm, too gayish for me, what if we just shake hands? :winkwink:

:1orglaugh:1orglaugh

Chelo your answer is wrong wrong wrong.

We've already given you the right answer.

Now you're just being ignorant. If you didn't want to be criticized you're at the wrong place.

Your answer is wrong. Your number sense is horrible.

I've seen little kids with a better sense of numbers, any kid that knows the difference between a big number and a smaller number.

Either way, this contest is against the GFY rules. Again you have no idea what you're doing, where you're doing it or how you're going about it.

Your answer is wrong. I'm a 5th year chemical physics student at the University of Guelph in Ontario, Canada, I know what I'm talking about with this kind of stuff and you are wrong.

Don't mind chelo, he's just incredibly bad with numbers/math/logic.

Just read the other posts by people who know what they're talking about and you'll be fine.

I can't wait for the answer to be revealed so people who know what they're talking about can disprove chelo and we can all have a good laugh at a dumb man trying to be smart.

The escape velocity needed to escape Earth's pull is around 25,000 mph so I guess you're on of those people who thinks the Sun is just 3 or 4 times the size of the Earth?
:1orglaugh:1orglaugh

:thumbsup

:1orglaugh:1orglaugh:1orglaugh:1orglaugh:1orglaugh

Looks like someone can't take the pressure of GFY.

Cry little girl, cry!!

Wild guess... 75,000 mph

still too low... :)

Bumping for an answer.

99,000 mph?

too high...
