Homework Statement



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?


Homework Equations



--none.


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?
