A swimmer having mass of 55 kg is diving in a swimming pool has an effective body area of 0.76 m2 as shown in Fig. 1. The tension in the direction of swimmer's leg is 1.5 kN when the legs make an inclination of 30∘ with the vertical direction. If the swimmer's hands bend about 40∘ with the flow of water and the magnitude of wave is 2.5 m/s. Determine the lift and drag forces and their coefficients and discuss on the results. Fig: 1

In the diagram shown, Block A is 34.5 kg and Block B is 11 kg. The incline on Block A's side makes an angle of 61.5∘ with the horizontal and the incline on Block B's side makes an angle of 29∘ with the horizontal. The coefficient of kinetic friction of Block A's incline is 0.16 and that of Block B's incline is 0.104 . Assume that Block A is initially (at t = 0) sliding up its incline at 5.2 m/s. Also assume the pulley is massless and frictionless. In your submitted work, be sure to show your neatly drawn free body diagrams for each mass (using a straight-edge). Identify each vector force (draw arrows) in the diagram and draw your axes for each diagram and show the component breakdown for each force. . . points will be lost for sloppy or incomplete drawings. You should have FOUR FBDs. . . one for each mass as Block A slides UP the incline (while Block B slides DOWN its incline), and one for each mass when Block A slides DOWN its incline (while Block B slides UP its incline).

A model airplane of mass m = 0.750 kg flies with a constant speed v = 35.0 m/s in a horizontal circle at the end of a control wire of length L = 60.0 m as shown in the figure below. The aerodynamic lift force F→lift (shown in the figure) acts at angle θ = 300 inward from the vertical, and the wire makes the same constant angle θ with the horizontal. Figure 8: Problem 2. (a) Draw and label all other forces acting on the airplane. Indicate the direction of the acceleration. (3 pt) (b) What is the radius of the circular path of the airplane? (3 pt) (c) What is the magnitude of the airplane's centripetal acceleration? (3 pt) (d) Find the tension in the wire and the magnitude of the lift force.
