At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 3.06 m/s, and an 71.1-kg person feels a 250-N force pressing against his back. What is the radius of a chamber?
an air puck of mass m1= 0.25 kg is tied to a string and allowed to revolve in a circle of radius R=1.0m on a frictionless horizontal table . the other end of the string passes through a hole in the center of a table and a mass of m2=1.0kg is tied to it. the suspended mass remains in equilibrium while the puck on the tabeltop revolves. a) what is the tension in the string b) what is the horizontal force acting on the puck c) what is the speed of the puck
A model airplane of mass 0.750 kg flies with a speed of 35.0 m/s in a horizontal circle at the end of a 60.0-m con- trol wire as shown in Figure P7.60a. The forces exerted on the airplane are shown in Figure P7.60b; the tension in the control wire, 0 = 20.0° inward from the vertical. Compute the tension in the wire, assuming the wire makes a constant angle of 0 = 20.0° with the horizontal. Circular path of airplane lift Wire | mg Б Figure P7.60
