A supersonic 2D airfoil has Mach number of 1.5. Find Lift curve slope of the airfoil. Correct Answer 0.062 per degree

Given, mach number M = 1.5 2D lift curve slope = 4 / (M2 – 1)0.5 = 4 / (1.52 – 1)0.5 = 3.57 per rad = 3.57/57.3 = 0.062 per degree.

Across the normal shockwave: 1) Stagnation pressure decreases whereas stagnation temperature remains constant 2) Mach number before the shockwave is always greater than one and after the shockwave, the Mach number need not be less than one 3) Across the shockwave there is a rise in pressure and temperature 4) The product of Mach number downstream of normal shockwave and upstream of normal shockwaves always one Which of the above statements are correct?
An airfoil is such that the drag produced by airfoil is 25N. Airfoil has chord of 2m and is experiencing dynamic pressure of 10Pa. Find the value of drag co-efficient for airfoil.
Flow separation causes lift to decrease with increasing angle of attack. This is inconsistent with the thin airfoil theory where the lift curve slope is 2π. This is a contradiction.

Rajat beats Nitin by 240 m in a 1560 m race. Then they go to race on a slope where Rajat starts from bottom of the slope and Nitin starts from top of the slope they run towards each other and when they meet Nitin has travelled 20 m more than Rajat. If the speed of any person on the slope, compared to normal speed, becomes (150/11)%  more in decline and 10% less in incline, what was the total length of the slope?
