## Main Question or Discussion Point

Just curious, but I was wondering if anyone knew how to find the maximum temperature of the surface of a shuttle/satellite upon reentering the atmosphere?

My guess would be:

F=-cv^2

[itex]E = \int F dx = \int -cv^2 dx[/itex]

PV=nRT --- I think PV has units of joules, maybe not, but assuming it is, so I'd say

[itex]\Delta[/itex]E=nR[itex]\Delta[/itex]T

But what would n be here? it's usually the moles of gas... so maybe

dE/dt=dn/dt*R[itex]\Delta[/itex]T ?

dn/dt would be some function of the velocity and the density of the atmosphere... I don't know, I'll just stop here for now lol.

what do you guys think?
