A freight train of mass 800 tonnes800\text{ tonnes}800 tonnes is travelling along a straight horizontal track. When the train is travelling at a speed of 24 m s-1, the brakes are applied, producing a constant horizontal resistive force of 160 kN160\text{ kN}160 kN. Find the distance the train travels while its speed is reduced from 24 m s-1 to 8 m s-1.
