A train is hauled up an incline of 1:40 by a effort of 20kN.Calculate the distance and the work done,when the train raised vertically at 30m?

distance traveled horizontally is 30x40 = 1200 m
distance on the slope = √(1200² + 30²) = 1200.375, rounded to 1200 m
work = Fd = 20 x 1200 = 24000 J or 24 kJ
