Homework Statement
Hello all, I have to determine the maximum height of a model rocket.
The rocket is launched at an 45 degree angle
The finale velocity is 15,69 m/s (v)
the extutevelocety is 14,23 m/s (c)
The total mass is 180 gram (m) or m0)
The emty mass is 52 grams (mf)
The mass pr sek is 0,45 kg/s (me)
And the total burntime is 0,28 sek (t)
Homework Equations
How can i calculate the hight at burnout, (i know how to calculate the last part) or all in one?
The Attempt at a Solution
I have tryed intregrating the rocket equation (v(t)) to get s(t), so i can calulate it with phytagoras, i got the equation from v(t) to:
but i have looked around to see it it was right, and i found this equation:
they give me different results, who is right, or are we both wrong?
Hope you can help
