Answer:

392 kJ

Step-by-step explanation:

Given that,

The total mass of the cabin and the passengers = 800 kg

The vertical distance between B and C is 50 m.

We need to find the increase of gravitational potential energy of the cabin and passengers when they move from B to C. It can be given by the relation as follows :


E=mgh\\\\E=800* 9.8* 50\\\\E=392000\ J\\\\\text{or}\\\\E=392\ kJ

So, the increase in gravitational potential energy is 392 kJ.
