1. The problem statement, all variables and given/known data Water falls onto a water wheell from a height of 2.0m at a rate of 95kg/s (a) If this water wheel is set up to provide electricity output, what is the max power output. (b) What is the speed as it hits the wheel? 2. Relevant equations Ep= mgh Ek= 1/2mv^2 3. The attempt at a solution I know that the water initally has both potential and kinetic energy as it falls but i am unsure as to how i use the rate in these equations and also which power equation(s) I use once i get to that stage.
