How much work does a steam crane need to do in order to lift a 108,500 kg locomotive back onto the track if the locomotive has been derailed into a ditch 3.25 meters below the level of the tracks?
Calculate the gravitational potential energy of the locomotive when it is on the track with repsect to its positon in the ditch.
How much power must the crane have to make this lift in 20.5 seconds?
