A "swing" ride at a carnival consists of chairs that are swung in a circle by 12.0-m cables attached to a vertical pole; the pole and the cable make an angle of 65.0 degrees above the horizontal. Suppose the total mass of a chair and its occupant is 220 kg. (a) Determine the tension in the cable attached to the chair. (b) Find the speed of the chair.
I can't figure it out!
