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].
