Help fo a Yr 12 Physics student.

[batema (Mark)]

Hi,

I have posted this in another area as I am unsure which forum to post this in.
I have a student who is doing a rocket launching assignment and is looking at the theory of getting a rocket into space. He is looking at trying to amalgamate the theory of mass loss during launch to acceleration and also including the changing atmospheric pressure and well as varying gravity at heights. He is trying to come up with one equation that can determine the velocity at various heights but ends up with too many varibles. Any advice if this is actually possible as the maths involved exceed my ability.

All I remember is the Rocket Equation...well I have forgotten how to use it now....but we did cover it in Astronomy class back in 1985

You want to launch a rocket to the moon? or Design inter-planetary trajectories ? Well fear not. Everything you wanted to know but were afraid to ask:-
