A 4.2 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 1.5 kg of water is raised 0.10°C?
You are not going to die. You just might not get the right answer.
