2. The 160-Mg train travels with a speed of 80 km/h when it starts to climb the slope as shown in Figure 1. If the engine exerts a traction force F of 1/20 of the weight of the train and the resistance FD is equal to 1/500 of the weight of the train, determine the time it takes for the train to stop after it has travelled up the slope a distance of 1 km.
