3. A swing ride at a carnival consists of chairs that are swung in a circle by 16.5-m cables attached to a vertical rotating pole, as the drawing shows. Suppose the total mass of a chair and its occupant is \( 172 \mathrm{~kg} \), the angle \( \theta \) \( =55^{\circ} \). Find the speed of the chair. \[ \mathrm{m} / \mathrm{s} \]
