In the display window of the toy store at the local mall, a battery-powered plane is suspended from a string and flying in a horizontal circle. A 0.631 kg plane makes a complete circle every 2.15 seconds. The radius of the circle is 0.950 m. Determine the velocity of, acceleration of, and net force acting upon the plane.
