## Homework Statement

A "swing" ride at a carnival consists of chairs that are swung in a circle by 12.0 m cables attached to a vertical rotating pole, as the drawing shows. (θ = 55.5°) Suppose the total mass of a chair and its occupant is 192 kg.

(a) Determine the tension in the cable attached to the chair.

N

(b) Find the speed of the chair.

m/s

## Homework Equations

Fc = mv^r

## The Attempt at a Solution

Ty = Fg

Ty = 9.8 * 192

Ty = 1881.6 N

T = 1881.6/sin 34.5

T = 3321.997

Fc = Tx

Fc = 3321.997 cos 34.5

Fc = 2737.74

Fc = mv^2/r

2737.74 = 192(v^2)/12

v = 13.081

The first part was right but what did I do wrong in the second part?
