An aircraft executes a horizontal loop at a speed of 720 km/h with its wings banked at 15°. What is the radius of the loop?
Speed of the aircraft, v=720 km/h=720×5/18=200 m/s. Acceleration due to gravity, g=10m/s2 Angle of banking = 15o For radius, r, of the loop, we have the relation: Ncosθ=mg Nsinθ=Rmu2 tanθ=u2/Rg r=u2/g tan θ =2002 / (10 tan15o) =4000/0.26 =14.92 km
