Power generation is given as rate of work done
Here the turbine generator is located at 120 m below the free surface
So here rate of work done is given as rate of potential energy


so we have

now we have

so the power generation potential will be 2234400 Watt
Answer:29.41 m/s
Explanation:
Given
Height of cliff 22.8 m
Height of river bank=2.4 m
width of river=60.0 m

Time travel to cover vertical distance=22.8-2.4=20.4 m



t=2.04 s
Range=60 m
Let u be the speed of car
ut=60
