Question 14 An airplane flies in a horizontal circle at a constant speed of 172 m/s. Banked for the turn, the wings of the plane tilt at 37.7o to the horizontal. Assume the lift force that keeps the plane aloft acts perpendicular to the wings. Find R, the radius of the circle in which the plane is flying, in km. HINT: This plane is not in equilibrium!
A model airplane with mass 0.758 kg is tethered to the ground by a wire so that it flies in a horizontal circle 29.7 m in radius. The airplane engine provides a net thrust of 0.796 N perpendicular to the tethering wire. (a) Find the magnitude of the torque the net thrust produces about the center of the circle. (b) Find the magnitude of the angular acceleration of the airplane. (c) Find the magnitude of the translational acceleration of the...

The model airplane has a mass of 0.90 kg and moves at constant speed on a circle that is parallel to the ground. The path of the airplane and the guideline lie in the same horizontal plane because the weight of the plane is balanced by the lift generated by its wings. Find the tension in the 17 m guideline for a speed of 19 m/s.

An airplane is flying at constant speed v=54 m/s in a horizontal circle of radius r=11 m. The lift force on the wings due to the air is perpendicular to the wings. At what angle to the vertical must the wings be banked to fly in this circle? θ = __________
You plan to fly a model airplane of mass 0.550 kg that is attached to a horizontal string. The plane will travel in a horizontal circle of radius 5.10 m. (Assume the weight of the plane is balanced by the upward "lift" force of the air on the wings of the plane.) The plane will make 1.10 revolutions every 3.50 s. (a) Find the speed at which you must fly the plane. (b) Find the force exerted on your hand...
