A 3.6 kg rock is initially at rest at the top of a cliff. Assume that the rock falls into the sea at the foot of the cliff and that its kinetic energy is transferred entirely to the water. How high is the cliff if the temperature of 1.1 kg of water is raised 0.14◦C? The acceler- ation of gravity is 9.81 m/s2 and the specific heat of water is 4186 J/kg ·◦ C.
