006 10.0 points A model airplane of mass 0.634 kg flies in a horizontal circle at the end of a control wire of length 45.4 m with a speed of 48.2 m/s. The forces exerted on the airplane are the pull of the control wire, its own weight, and aerodynamic lift, which acts at 29.7° inward from the vertical as shown in the figure litft Compute the tension in the wire if it makes a constant angle of 29.7 with...
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.
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...
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!
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 = __________

A jet airplane is in level flight. The mass of the airplane is ?=8950 kg. The airplane travels at a constant speed around a circular path of radius ?=9.77 mi and makes one revolution every ?=0.129 h. Given that the lift force acts perpendicularly upward from the plane defined by the wings, what is the magnitude of the lift force acting on the airplane? An airplane banked inward such that its wings make an angle theta with the horizontal travels...
The model airplane in Figure 5.6 is flying at a speed of 24.5 m/s on a horizontal circle of radius 17.0 m. The mass of the plane is 0.994 kg. The person holding the guideline pulls it in until the radius of the circle becomes 12.3 m. The plane speeds up, and the tension in the guideline becomes four times greater. What is the net work done on the plane?
