Water in a creek is at T = 25°C and is flowing at 2 m/s when it reaches the top of a waterfall. It falls 50 meters into a pool. The velocity leaving the pool is negligible. The creek, waterfall, and pool can be modeled as at steady state and adiabatic.

A. What is the velocity of the water at the point that it hits the surface of the pool?

B. Assuming the heat capacity of liquid water is constant at 4.19 kJ/kg⋅8C, and neglecting any external heat source, what is the temperature of the water in the pool?
