Problem- Water flows over a waterfall 125m in height. For a system of 3.25 kg H2O that does not exchange energy with its surroundings
a) What is Ep at the top of the falls with respect to the base of the falls?
b) What is Ek just before the water strikes the bottom?
c) What change has occurred in the system after the water enters the stream below the falls? (Both in words and numerically)
Please show me how work it out above problem
