In what case is a lot of work done: when lifting a 50 kg load to a height of 6 m or when a 15 kg load falls from a height of 2 m?

Given: m = 50kg, h = 6m, m = 15kg, h = 2m.
Find: A
Decision:
A = Fs = Ftyazh = mgh = 50kg * 10 * 6m = 3000J
A = Fs = Ftyazh = mgh = 15kg * 10 * 2m = 300J
Answer: when lifting a load, a lot of work is done.
