okay i will do a velocity study

so velocity. i assume you mean the velocity in a rocket in zero gravity of COURSE

____________________________________________________________________

so if a rocket has 200 Kn thrust (t)

a mass of 20 tons (m)

velocity of the fuel from the engine of 1600m/s we can call (ev)

60% of the rocket is fuel (finished mass is 8 tons)

if we take tsiolkovsky's rocket eqation (no i didn't google all of this. maybe a bit Kappa) (yes that kappa won't work but whatever i like kappa) (what you do't know what kappa is well thats your fault) (what google it) ( i am using alot of brackets :D)

delta-v = 1600 x 20/8 = 4400 delta-v

but we are not done

now we could take 20/8 to get 12 12/2 = 6 8+6 = 14

1600x200/14/5 = around 4400 delta v

so velocity a setting on garageband

yet a thing that makes a rocket go into the sky

btw rockets turn
