Question
the steepest railroad track that allows trains to move using their own locomotion and the friction between their wheels and the track is located in France. The track makes an angle of 5.2 degrees with the horizontal. Suppose the rails become greasy and the train slides down the track even though the wheels are locked and held in place with blocks. If the train slides down the tracks with a constant velocity, what is the coefficient of kinetic friction between the wheels and track? (Hint solve with mass as a variable)Explanation / Answer
for constant speed,
mgsin = mgcos
= tan
= 0.091
