 Newton's Third Law - Water Rocket Experiment by ETDtogo 


fy = -9.81+if (t<0.5,T,0)

where T is 23.4 N.
what the model suggests is the thrust is 23.4 acting for 0.5 seconds at beginning of the video.


mass is constant
thrust is constant at 23.4N

my observation

the flight path is roughly close the real motion.


of course, the model is flawed, but that is the nature of science, a better model gets made by building on other people's idea.


can you build a better model?
