All, this rambling on for nothing. Why don't you just admit you were wrong and stop embarrassing yourself further.

Anyone out there with a rational brain, do the maths. No need for comlicated bollocks or anything. Just do the maths for how a rocket can accelerate to 17,000 mph in 8 minutes

It's been shown to you, and it isn't complicated at all. Let's do it again:

to go from 0 to 17,000 mph over 8 mins means they accelerate at 15.8 metres/s/s. This means that for every second they are traveling 15.8 m/s faster. So after 1s they are going 15.8 m/s, after 2 seconds they are going 31.6 m/s and after 3 seconds they are going 47.4 m/s and so on...

To calculate g-force:

1 g = 9.8 m/s/s

therefore

15.8 / 9.8 = 1.61

So the average g-force going from 0 to 17,000 mph in 8 mins is **1.61g** - this is only slighty higher than the g-force you will experience in your Bugatti Veyron as you go from 0-100 kph. For the last minute of burn they do in fact reach 3g, then they turn the main engines off and go to zero-g.

Have another go, crabby.

There's no need, his maths is spot on.

Have another go, mathsman.

Have another go at

*what*? The answer is correct. You obviously don't

*like* the answer because it clearly and unequivocally disproves the point you're trying to make, but that's

*your* problem and on one else's, so please drop it.

You asked us to guess at the acceleration needed, but it's not necessary to guess at all. An exact answer can be easily calculated given the well-defined problem presented.

What's

*your* guess? Was it your 5 mi/s

^{2}, which is more than 800g? That is, indeed, an unsurvivable acceleration, but would achieve orbital velocity in one second (less, actually - have you figured out how much less yet? Can you, sceptimatic?) Fortunately, there is no need to accelerate the shuttle to this velocity in less than a second, so the needed acceleration is considerably less (by almost 3 orders of magnitude [do you know what that means, sceptimatic?]), an easily-survivable 1.6g. This shows why, in the real world, such things are calculated by people who know what they're doing, not guessed.

The thing is, any arbitrary acceleration can be used to accelerate an object from zero to 17,000 mi/hr, it's just that it takes longer with lower acceleration. This is basic physics and algebra. It's quite handy knowing how to apply these, especially in discussions like this. Your rants about undesired (but nonetheless correct) results make you look petulant.

It's becoming clear that you are hostile to math because you can't do it. This puts you at a distinct disadvantage to the many people who

*can* do middle-school and higher level math (that's usually grades 6 to 9 in the US), which must be embarrassing, so you try to dismiss it as totally useless. It isn't.
