A model airplane of mass 0.750 kg flies with speed of 35.0 m/s in a horizontal circle at the end of a 60.0-m control wire as shown in Figure P7.60a. The forces exerted on the airplane are shown in Figure P7.60b; the tension in the control wire is inward from the vertical. Compute the tension in the wire, assuming the wire makes constant angle of 20.0° with the horizontal.
