How can I plot the altitude of a capsule during re-entry?

[phiska]

Hi,

I need to plot as a function of time, the altitude of a capsule bringing astronauts back from space.

I have all the values required in order to calultate it but I'm not sure how i plot it as a function of time?

Is it simply a differential matter?

Your help is much appreciated!

Thanks

phiska,

What are the "values" that you have?

re-entry angle, ballistic coefficient, initial altitude, initial velocity, density of atmosphere at different altitudes etc
