An airplane with a Clark Y airfoil cross-section weighs 3500 lbs. The chord length is 6ft and the wingspan is 36 ft. Determine the:
a) Minimum speed and power to take off, if the angle of attack is 12.4 degrees.
b) Power to cruise at 150 mph at an altitude of 15,000 ft.
c) % increase in power if the plane is cruising 150 mph at 10,000 ft.
d) Stall speed at landing
