10.0 kg of water is about to fall over a cliff in a waterfall. The height of the cliff is 115 m. Determine the potential energy of the mass of water considering standard gravity on Earth.
Given: m = 10.0 kg; g = 9.81 m/s2; z = 115 m
What will be an ideal response?
PE = mgz = (10.0 kg)(9.81 m/s2)(115 m ) = 11,280 J = 11.3 kJ
