A cable car cabin of mass 2500 kg is at point A at the top of a mountain slope. As it travels down the track to point B, its gravitational potential energy store decreases by 441,000 J441,000\text{ J}441,000 J.
Calculate the vertical height h h\,h shown in the diagram.
(gravitational field strength, g=9.8 N/kgg = 9.8\text{ N/kg}g=9.8 N/kg)
