The power developed by the second crane is half that of the first crane.
<h3>
Power</h3>
Power is the ratio of the amount of energy to the total time. It is given by:
Power = Energy / time
Energy = mass * g * h
Let g represent the acceleration due to gravity and h the vertical height, for the first crane:
Power = 1200gh/20
For the second crane:
Power = 1200gh/40
Ratio of power in second crane to that of first = (1200gh/40) / (1200gh/20) = 0.5
The power developed by the second crane is half that of the first crane.
