A 3.0 kg rock is initially at rest at the top of a cliff. Assuming 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 1.0 kg of water is raised 0.10 degree celsius.
I found the height to be 14.22 m, but I'm not sure if this is correct. Please tell me if I got the right answer or if I'm doing something wrong.
