A maglev (magnetic-levitation-suspension) train massing (1.5 × 10' kg coasts up a hill rising at an (angle of 15° above the horizontal at an initial speed of 360 km/hr. a) If the train is effectively coasting with no friction, what is the maximum distance up the grade (that is, along the hill) that the train could travel before it coasts to a stop? b) If the train's engines generated 3.750 x 107 W of energy to push the train forward on level ground at 360 km/hr, how much force would they have to exert to do so? 360km 1000m
