A train of total weight 300 tons travels up a 1 :200 incline. The total frictional resistance can be taken as 450N per ton. What is the power required to maintain a steady 50km/h speed up the slope?

Question
A train of total weight 300 tons travels up a 1 :200 incline. The total frictional resistance can be taken as 450N per ton. What is the power required to maintain a steady 50km/h speed up the slope?
Expert Solution
Step 1
We will first find the incline, and then the component of force acting along the inclined plane. The frictional force will be directed downwards along the plane because the train is moving upwards. Finally, the power will be given by force multiplied with velocity.
