The highest mobile crane is capable of lifting 30 tons of cargo to a height of 160 meters

The highest mobile crane is capable of lifting 30 tons of cargo to a height of 160 meters at a speed of 7.2 km / h. How much power does it develop?

Initial data: m (the mass of the load that the mobile crane is capable of lifting) = 30 t (30 * 10 ^ 3 kg); h (the height to which the crane must lift the load) = 160 m; V (lifting speed) = 7.2 km / h (2 m / s).

Reference values: g (acceleration due to gravity) = 9.8 m / s2.

The power that the highest mobile crane develops can be determined by the formula: N = F * V = m * g * V.

Calculation: N = 30 * 10 ^ 3 * 9.8 * 2 = 588 * 10 ^ 3 W (588 kW).

Answer: the mobile crane develops a power of 588 kW.
