A model airplane of mass 0.700 kg flies with a speed of 35.0 m/s in a horizontal circle at the end of a 66.0-m-long control wire as shown in Figure (a). The forces exerted on the airplane are shown in Figure (b): the tension in the control wire, the gravitational force, and aerodynamic lift that acts at ? = 20.0° inward from the vertical. Compute the radius, lift, and tension in the wire, assuming it makes a constant angle of ? = 20.0° with the horizontal. Use g=9.8 m/s2. Determine its lift, radius, and tension.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
