The power of a crane, which lifts a mass of 1000 kg to a height of 20 m in 10 s is: (g=9.8 m/s²)

Solution & Explanation

Related Formula
P = (W)/(t) = (mgh)/(t)
Core Logic
P = (1000 × 9.8 × 20)/(10) = 19600 W = 19.6 kW
Pattern Recognition

Gravitational potential work divided by time gives mechanical power.
