I made a model rocket.
Total weight - 1.635 N (wet).
It has a custom solid rocket motor with black powder producing 5 N for 15 sec.
So how can I calculate how high will it travel?
Some equations would be helpful....
My rocket is guided , works on thrust vector control , i could've just flown it to find the awnsere of my question but in future , i have plans of propulsive landing so i might need to have these precise calculations.
i did some research and found out Thrust - (mass x 9.8)/mass is my acceleration , and this will apply for all the cases , also during descent?? Why doesn't the acceleration of 9.8 need to be deducted from my final acceleration?
