A two-dimensional, flat plate is inclined at a positive angle of attack in a supersonic air stream of Mach 2.0 (M1) and P1 = 50 kPa. Below the plate, an oblique shock wave starts at the leading edge, making an angle of 420 with the stream direction. On the upper side, an expansion occurs at the leading edge.

(a) Find the angle of attack of the plate.
(b) What is the pressure on the lower surface of the plate?
(c) What is the pressure on the upper surface of the plate?
