A body is reentering the earth's atmosphere at a Mach number of 20. In front of the body is a shockwave, as shown in Figure P4.6. Opposite the nose of the body, the shock can be seen to be normal to the flow direction. Determine the stagnation pressure and tempera- ture to which the nose is subjected. Assume that the air behaves as a perfect gas (neglect dissociation) with constant y = 1.4. The ambient pressure and temperature are 1.0 kPa and 220 K, respectively.

Question

Please answer the second question related to the what is the temperature of the sun in detail. Dont solve the problem. Thanks!~

What is the temperature of the Sun (google for the answer)? What is the
re-entry temperature of the Space Shuttle (google for the answer)? Why
don’t you burn up at the reentry temperature that you've calculated for this
Mach 20 flow? The answer to this question will lead you to recognize that
Figure 4.6 is wrong and that the body should actually re-enter the Earth's
atmosphere in the opposite direction. (ie.. blunt/flat surface first.)
