Hey Bambi, yeah 69 is about the only number i love. :o I would be intrigued to know how you came about the theory that i love mathematic stuff. This should make great reading :D:D

Add more

(tell me if i guess wrong)

khunlungphudhu - its TH name ..ancient hi-so guy and pooh dee

sadako- sound like a ghost from "the ring" movie

And for todays lesson boys and girls, we are going to build a rocket. Homework to be handed in to me tomorrow evening.

Let's use an Estes Alpha III, to keep it basic:

Weight: 1.2 ounces empty. I will add 0.7 ounces for the engine.

Diameter: 0.976 inches

Motor: C6-7 (we'll use a big one for this rocket)

Now let's follow the equations above and see what we get:

Compute the Useful Terms

Mass of the rocket M = (weight in ounces)/16/2.2 = (1.2+0.7) / 16 / 2.2 = 0.05398 kg

Area of the rocket: A = pi*r^2 = 3.14*(0.5*0.976/12*0.3048)^2 = 0.000483 m^2

Compute wind resistance factor: k = 0.5*rho*Cd*A = 0.5*1.2*0.75*0.000483 = 0.000217

A C6 motor has a nominal impulse of 10 N-s and thrust of 6 N. The "rating" cited above applies to the impulse, giving us an actual impulse for an Estes C6 of 10*90% = 9 N-s.

Compute the burn time t = I / T = 9 / 6 = 1.5 sec.

The gravitational force = M*9.8 = 0.05398*9.8 = 0.529 newton

Compute My Terms

q = sqrt([T - M*g] / k) = sqrt([6 - 0.05398*9.8] / 0.000217) = 158.8

x = 2*k*q / M = 2*0.000217*158.8 / 0.05398 = 1.277

Now the good stuff:

v = q*[1-exp(-x*t)] / [1+exp(-x*t)]

= 158.8*[1-exp(-1.277*1.5)] / [1+exp(-1.277*1.5)] = 118.0 m/s

if this number doesn't mean anything to you, multiply by 2.237 to get velocity at burn-out in mph: 118.0*2.237 = 264.0 mph! And you won't get a ticket!

yb = [-M / (2*k)]*ln([T - M*g - k*v^2] / [T - M*g])

= [-0.05398 / (2*0.000217)]*ln([6 - 0.05398*9.8 - 0.000217*118.0^2] / [6 - 0.05398*9.8]) = 99.95 m

remember this is the height reached during boost. Multiply by 3.3 to get it in feet: 99.95*3.3 = 329.8 feet.

yc = [+M / (2*k)]*ln([M*g + k*v^2] / [M*g])

= [+0.05398 / (2*0.000217)]*ln([0.05398*9.8 + 0.000217*118.0^2] / [0.05398*9.8])

= 236.8 m = 781.4 feet.

Notice: the rocket goes more than twice as far after the burn as during the burn!

AND THE TOTAL ALTITUDE IS... yb + yc = 329.8 + 781.4 = 1,111 feet :o

:D:D

:D :wacko:

i reckon the final answer = 69

:o Correcto Mundo but don't tell anybody else Bambi, they have still got to hand their homework in :D

Khun Jean because it is my name and i like it. So much easier than hiding behind a nickname.

I had another one before although not here. It was "Brainless".

I changed it because it was to revealing.

My friends have called me zaz for a very long time so this is the name practically everyone knows me by.

I'm a Libertarian.  I believe that governments should leave people alone as long as they're not hurting or stealing from anyone else.

Libertarian Party

CATO Institute

So , read any good books lately?

OOps sorry. Libertarian. not librarian! :D

Anyway

23 x 3 = well I could tell you the answer in Russian, but its rather a mouthfull :D

23 x 3 = sometimes only 34 and half (think about it) :o

23 x 3 = sometimes "I no like*
