Homework Statement
I need to find out the rockets max velocity and max altitude. My teacher gave us an example but everytime i use the stuff we know his answer doesn't match mine.
So we know: Rockets mass=23 grams
mass of engine=16.2 grams
mass of propellant=3.12
average thrust=8 Newtons
burn duration=.5 seconds
His max velocity=101.37
His max altitude=549.621
Homework Equations
The equations he gave us are:
x = Xo + vt, v=Vo +at, x = Xo+Vot+.5at^2, and f=ma
x=distance, v=velocity, t=time, a=acceleration, f=force
The Attempt at a Solution
Whenever i plug all the stuff in i come up with a Max velocity of 102.04
Then i really don't know where to go from there to even check his altitude.
Please help
thanks
