A model airplane of mass 0.770 kilogram flies in a horizontal circle at the end of a 66.0 meter control wire, with a speed of 35.0 m/s. Find what is the tension in the wire if it makes a constant angle of 20.0 degree with the horizontal. The forces exerted on the airplane are the pull of the control wire, the gravitational force, and aerodynamic lift, which acts at 20.0 degree inward from the vertical?
