Banking Plane: Planes turn by banking (that is, by tilting the plane at an angle). The lift force that the air exerts on the wings points perpindicular to the wings, as shown in the free body diagram on the right. If a plane is going at 100 m/s and the pilot wants to turn in a horizontal circle of radius 1.0 km, at what angle should she tilt the plane? You can assume there are no forces acting on the plane other than the lift force and gravity. (In the diagram, the plane is heading away from us, into the page, and is turning to our right.) mg Flift

A model airplane of mass 0.75 kg flies in a horizontal circle at the end of a 60 m control wire, with a speed of 35 m/s. Determine the tension in the wire if it makes a constant angle of 20 degrees with the horizontal. The forces exerted on the airplane are the pull of the control wire, its own weight, and aerodynamic lift, which acts at 20 degrees inward from the vertical as shown in the diagram

A ball of mass M is on a horizontal surface with negligible friction. One end of a string is attached to the ball so that it is spun in a horizontal circle of radius R at a tangential speed vo, as shown in Figure 1. A free-body diagram for the ball at an instant in time is shown in Figure 2. The magnitude of the tension force is also indicated in Figure 2. Which of the following equations represents the centripetal acceleration of the ball if its tangential speed is increased to 2vo ?
