- 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 diagramA 450.0 kg roller coaster is traveling in a circle with radius 15.0m. Its speed at point A is 28.0m/s and its speed at point B is 14.0 m/s. At point A the cart is already moving with circular motion. a) Draw free bodydiagramsfor the cartatpointsAand B(two separate free body diagrams). b) Calculate the acceleration of the cartat pointsAandB(magnitude and direction). c) Calculate the magnitude of the normal force exerted by the trackson the cartat point A. d) Calculate the magnitude of the normal force exerted by the tracks on the cart at point B.1. A racing bicycle with rider has a combined mass of 85 kg. The racer is on a velodrome (circular racing track) that has banked curves. The surface is banked at an angle of 35° from horizontal. The track has a radius of 60 m. a) Draw a free-body diagram of the racer viewing the racecar from the front (left) and from above (right.) Ignore friction. Indicate the direction of the acceleration of the racer next to your diagram. b) Based on your free-body diagram do you think the car could possibly stay on a circular path (the track) without friction? Explain. c) Which of the forces you drew has a component in the same direction as the acceleration? Explain. d) Write down your force equations and solve for the acceleration of the racer moving at a constant speed around the track with no friction. (Hint: Use the direction of the acceleration as one of your axes. Do not use along-the-incline and perpendicular-to- the-incline as your axes.) e) What speed would the racer have with this…
