I wanted to figure out the temperature(t2) of any object based on things such as its specific heat capacity, re-entry speed, etc.

Work: W = Fy

Force by Air: FD = 1/2pv2CDA

Energy-temperature relationship: Q = mc(t2 - t1)

Setting things equal & solving for t2 gives:

t2 = (1/2pv2CDAy+mct1) / mc

(I'm sorry I could not get latex to format all of the formulas correctly so I formatted none of them...)

So, how accurate is this equation in describing temperature gain through freefall back down to earth?
