Halliday, Resnick & Walker β Potential Energy and Conservation of Energy: Problem 125
Approximately \(5.5 \times 10^6 \text{ kg}\) of water falls \(50 \text{ m}\) over Niagara Falls each second. (a) What is the decrease in the gravitational potential energy of the waterβEarth system each second? (b) If all this energy could be converted to electrical energy (it cannot be), at what rate would electrical energy be supplied? (The mass of \(1 \text{ m}^3\) of water is \(1000 \text{ kg}\).) (c) If the electrical energy were sold at \(1 \text{ cent/kW} \cdot \text{h}\), what would be the yearly income?
