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=720km/h=7205/18=200m/s.
Acceleration due to gravity,g=10m/s2Angle of banking =15oFor radius,r, of the loop, we have the relation:Ncosθ=mgNsinθ=Rmu2tanθ=u2/Rgr=u2/gtanθ=2002/ (10tan15o)=4000/0.26=14.92km
