An airplane is flying in a horizontal circle at a speed of 420 km/h (see the figure). If its wings are tilted at angle θ = 42.0∘ to the horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an "aerodynamic lift" that is perpendicular to the wing surface. Number Units
![A model airplane of mass m = 0.750 kg flies with a speed of v = 35.0 m/s in a horizontal circle at the end of a 60.0 -m-long control wire as shown in the figure below. a b The forces exerted on the airplane are shown in figure on the right; the tension in the control wire T→, the weight mg→, and aerodynamic lift force F→L that acts at θ = 20.0∘ to the left of the +y-axis, as shown. The tension force T― makes an angle of θ = 20.0∘ below the horizontal, as shown. Calculate (a) the tension in the control wire [20 pts] and (b) the lift force FL [5 pts].](https://www.doubtrix.com/uploads/editor/6587265815GiHjvresbU.jpg)
