Not sure if that is a good idea because of orbital decay.... but on the other hand i'm pretty sure it's jebediah and not jebidiah

Well, you should because it is crazy OP ! (It will probably get nerfed in 1.0) I also never use the Mk2 Inline cockpit because there is no Mk2 nosecone to put in front of it ! (If anyone know what to put in front of it to make it aerodynamically stable, or just look nice, let me know). Same goes for the Mk2 probe core...

Agreed with the "making simple mistakes part ! i did not ask after what time does the car reach 36km/h but after what distance down the slope ! good try though it is not off topic since no one has yet given the answer in meters ! (some are having fun with the fountain problem it seems )

well, i am aware that it can be calculated, but when you design your rocket, you don't know how much deltaV your transfer will need yet. you only precisely know it once you are in orbit and your maneuver node is set up, because the deltaV needed can vary very much depending of planetary alignement, starting orbit etc ! (and we all know that a .1m/s can make the difference) i think that you see what i mean now !

hardcore redundancy !

oO what the hell do you need that for ?

The stayputnik probe. It doesn't even have SAS.

It better do !

I'll guess i'll rely on my plan B tonight : at least Game of thrones' hacked episodes won't be scrubbed ! Damn those anvil clouds ! (i actually love clouds but here... they are just being annoying)

Noooooooo

SpaceX webcast works much better than NASA's ! ​ITS HAPPENING

Yup, although the streaming works terribly bad (at least for me) as usual... I hope spacex's webcast will work better than NASA TV's one. (its not even my connection speed !)

well no rep for you my friend the calculation is math actually, and it's another interesting thing (although i must agree that right there the calculation is easy and boring)

Are those real colors, or are they added to highlight something ?

Yeah, but just give the plain answer in m so that others can solve it without seeing the solution immediately

Okay, here is the next problem : (harder) max time allowed to resolve it : 20 minutes ! the guys who love calculations about work and energy will be happy A 1600kg car is on a 6° inclinated slope. The car is old and rusty : the force of friction due to its movement will always be 800N (whatever its speed, its to make things simpler). The car is abandonned and has no initial velocity. After what distance on the slope does the car reach 36km/h ? EDIT : the first to solve it gets some rep

I forgot on what website we can watch the stream... Can anyone please tell me ? thanks EDIT : i think i found it, its on spacex webcast right ?

Its pretty fun to realize that my fairly easy problem created a big discussion ! (i can give you a harder (better also) one if some of you are interested) I don't get why some people think that the flow means nothing and cannot be used... Well, kohai khaos explained it very well. btw, you might have realized that this fountain is not the common foutain you find around in town 200m high and 500l/s flow, thats a lot !

I wanted to lift my (over-engineered) duna outpost into LKO in a cheap way in career mode, ended up all-solid : Short orbital refueling and to Duna we go ! After arriving at Duna i realized it was so overkill it was the good time to hop on Ike on the way to duna, land, and back up to orbit, thus accomplishing 2 contracts at once instead of the planned one only Finally, i put up a basic Mun base in one go, because i felt too lazy to assemble it on the ground or in orbit, i instead used a huge rocket (no pics :/ ) to lift it ! As you can see its pretty much a bunch of spacetape linked together with modules There are also a couple escape pods (that can make it only to Kerbin)

or, if you're really into useless , additional, superfluous calculations, you can get the velocity of the "exhaust" water at the base of the fountain using the kinetic energy, and then F=ma, resolve the time equation, have some fun with primitives and get the same result

if the weather is too bad i hope that they will reschedule the launch and not just launch falcon 9 without even trying to land it like last time... I really prefer the older dragon logo, the one with the wings. the new one is seriously meh if you ask me

yup thats it well if you get lazy and use 10m.s^-2 for g instead of 9,81 to do it more easily in your head you get exactly 200m (obviously, duh) this exercise is supposed to be about the foutain of geneve wich IRL is about 140m high because of energy "losses"

that's what i thought, thanks

A small physics thing i thought I'd share here : our physics teacher (3rd year of highschool, france, we students are about 18) gave us this : a fountain is powered by a 10^6 W pump. The flow in the fountain is 500L of water per second. What height does the water reach ? ( Neglect all air resistance, jupiter's gravity influence and such and the fountain is vertical) It's not very difficult but kinda fun (somehow). It took me a few minutes, i'm sure most guys here will get it in seconds !

Technically, Vf=Vi+at does kill you though, since the energy that will break your skull is vf^2*m*1/2 Right ? --->or maybe we're not speaking about the same thing : i'm french and we might not use the same names fofr variables as in english Tell me
