Fig. 1

A ring is threaded on a fixed horizontal bar. The ring is attached to one end of a light inextensible string which is used to pull the ring along the bar at a constant speed of $0.5\text{ m s}^{-1}$ . The string makes a constant angle of $24^{\circ}$ with the bar and the tension in the string is $6\text{ N}$ (see diagram). Find the work done by the tension in a period of $8\text{ s}$ .
