You must include the units of the angle (percent? degrees? radians?) and the speed (mph? kph? m/s?). Just writing don a number os not enough.
You also did not ask a question.
Perhaps they wanted to know how far the train coasts up the incline befre movong backwards.
Is so, try using conservation of energy. The initial kinetic energy gets converted to additional poteneital energy.
