0A train of length l =900m running on a horizontal track with its engine off starts moving up a hill of uniform inclination theta = 9.2 degree to the horizontal. If n=0.6 fraction of length of the train rises the hill before it starts moving back due to gravity, how much time the train spends on the hill ? Assume all the resistive forces negligible, distribution of mass uniform in the train and no impact at the beginning of the hill. Acceleration due to gravity is g.
