A little question: as a planet (such as jupiter) orbits the sun, both the planet, and the sun orbit the same point of the centre of mass. how do you calculate where that centre of mass is?
(2 body problem only)

Downrange
Hey, is there any "sensible" way of calculating downrange other than some hefty trig between all the given points on that pitch-time table?
thanks

Curve Points
hey, I've been browsing that site you gave me and I've found a table full of velocities and angle of pitches... http://history.nasa.gov/ap15fj/csmlc/2-03.gif

Curved Launch
Hey, Help is again needed.
i have done most of the mathematics required for variable mass, but before i get my variable acceleration formulae i need to know the path the rocket took.
I tried looking online, and could not find any specific references, should i model it as a...
model
Enigma, thanks for your help...
i realize it seems a lot for a 1st year to bite off right now, but it's something I've been wanting to do for ages.
As for the maths, hit me with as much math as you like! i did further maths at A level, so that's covering things like 2nd and 3rd order...
curved path
use the fact that in circular motion, F=(mv^2)/r.
after a bit of fiddling that gives you the ratios of the circles:
r(p) = radius for proton path
r(e) = radius of electron path
m(e) = mass of electron
m(p) = mass of proton
v = velocity of particle
B = mag field strength...
hi, I'm an undergraduate from the University of Newcastle Upon Tyne, and I'm trying to develop an accurate model of a launch of a saturn V rocket for a project.
i have access to the technical specs like fuel capacities, consumption rates, etc. but i need help on some of the harder...
