(adsbygoogle = window.adsbygoogle || []).push({}); 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?
