1. The problem statement, all variables and given/known data water flows over a section of niagara falls at the rate of 1.2*10^6 kg/s (kilograms per second) and falls 50.0 m (meters). How much power is generated by the falling water? 2. Relevant equations --none. 3. The attempt at a solution gravitational potential energy (PE grav)=mgh (mass*gravity*height) PE grav=(1.2*10^9 g/s)(9.81)(50.0 m) PE grav=588,600,000,000 but PE is measured in joules. and power is measured in watts. so how do i get from PE to W?
