The engine power of the helicopter is 125 kW. The weight of the helicopter is 2000 kg. How long does it take for the helicopter to rise to an altitude of 250 m?
Let’s solve this problem using the Energy Conservation Law, then:
P * t = mgh. Let us express t from this equation.
t = mgh / P = 5000000/125000 = 40sec
