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 stone that is connected to a string is being rotated horizontally. The stone completes one full circle every second; and the magnitude of the tension in the string is F-. What happens to the tension in the string if the stone speeds up such that it goes around the circle twice every second while the radius stays the same. O The magnitude of the tension increases to twice its original value. O The magnitude of the tension increases to four times its original value. O The magnitude of the tension reduces to one-fourth of its original value. O The magnitude of the tension is unchanged. O The magnitude of the tension reduces to half of its original value.
A tennis ball connected to a string is spun counterclockwise around in a vertical, circular path at a uniform speed. The ball has a mass m = 0.16 kg and moves at speed v = 2.4 m/s. The circular path has a radius of R = 0.26 m. The ball is at the bottom of the circle as shown. What is the magnitude of the tension force on the ball at this instant, in Newtons? Use g = 10 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
A small 0.250-kg object is attached to a string (see figure), where it swings in a section of a vertical circle of radius 2.50 m. Find the magnitude of the tension in the string when θ = 28.0°, the speed of the object is 4.50 m/s
As shown above, a bead is at the end of a string and moves in a horizontal circle with a constant speed of 1.43 m/s. The length of the string, L, is 185 cm and the mass of the bead is 27.0 g. The angle, 0, is known to be 19.0°. As outlined below, use two different approaches to find the tension, T, of the string. Assume that the air resistance is negligible. Although this is a multiple-choice question that you will answer on Bb and I will not be collecting the details of your work, I urge you to follow the steps outlined below to solve it. We will do the FBD of the bead together in class before this problem is due. Hint: be careful with your units. (a) Use the GFS method to show and explain each step of your work. (b) Draw a sketch of the bead. Next, clearly draw and label the FBD of the bead, showing all the external forces that are acting on it. Each external force must be represented by an arrow that is properly labeled. Be sure to show explicitly the x and y coordinate system you…
