A3. A model airplane of mass m flies with a speed | v| in a horizontal circle at the end of a control wire of length I. Circular path of airplane Wire a) Draw a free-body diagram for the force acting on the plane. Assume that the aerodynamic lift force acts in a direction perpendicular to the wings of the airplane, and that the wire is at an angle 0 below the horizontal. [2 points] b) Calculate the lift and tension forces if m = 0. 750kg, |v| = 35.0m/s, L = 60.0m and 0 = 20.0. [3 points]
