A "swing" ride at a carnival consists of chairs that are swung in a circle by 11.5 m cables attached to a vertical rotating pole, as the drawing shows. Suppose the total mass of a chair and its occupant is 204 kg. (a) Determine the tension in the cable attached to the chair. (b) Find the speed of the chair.

It depends on the angle the chairs are indicating
Not sure of B, but I can tell you A.

T = mg / (cos theta)

T = (204*9.81) / cos (theta)

The angle should have been given to you.
