## Homework Statement

Consider a waterfall that is 120m high. How much warmer is the water at the bottom of the waterfall than at the top? The specific heat capacity of water is 4186J/ kg*°C.

## Homework Equations

Conservation of Energy

## The Attempt at a Solution

Eg [top] = Ek [just before the water hits the ground]

(m)(g)(h) = 1/2(m)(v)^2

I don't know how to compare the warmness of the top to the bottom, or how to get it calculation-wise. Does this have to do with:

E = (m)(c)(T)?

Where "E" is the heat energy?
