SUMMARY
The crane lifts a 1500 kg car vertically 20 meters, resulting in a gain of potential energy calculated using the formula Eg = mgh, yielding 294,000 Joules. The energy transferred by the crane to the car is also 294,000 Joules, indicating that the crane does an equivalent amount of work. The discussion highlights the relationship between energy transfer and work done, emphasizing that in this scenario, the crane's work is directly related to the potential energy gained by the car.
