Assuming the rocket reaches a target of 30K ft AGL:
T_static = 59F - .00356(F/ft) * h_{max_v} (ft)
Therefore,
T_stag = (59F - .00356(F/ft) * h_{max_v} (ft)) + (4.9776*10^{-4}) * (v_2 * cos(λ))^2
v_2 = Mach 2 = 2*343 (m/s) = 686 (m/s)
T_stag = (59F - .00356(F/ft) * h_{max_v} (ft)) + (4.9776*10^{-4}) * (686 (m/s) * cos(λ))^2
Note that the first half of the sum is in degrees F whereas the second half of the sum will be in degrees K.
