Helicopter engine power 300 kW. helicopter weight 2t. how long will it take to climb to an altitude of 1500m?

These tasks: N (engine power of the helicopter under consideration) = 300 kW (300 * 10 ^ 3 W); m (helicopter mass) = 2 t (in SI m = 2 * 10 ^ 3 kg); h (the height that the helicopter should gain) = 1500 m.

Constants: g (acceleration due to gravity) ≈ 10 m / s2.

The duration of the ascent of the helicopter under consideration to an altitude of 1500 m is determined by the formula: t = A / N = ΔEp / N = m * g * h / N.

Calculation: t = 2 * 10 ^ 3 * 10 * 1500 / (300 * 10 ^ 3) = 100 s.

Answer: To climb to a height of 1500 m, the helicopter will need 100 seconds.
