## 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
