He rock falls into the sea at the foot of the cliff

Reference no: EM13543459

A 4.3 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. The specific heat of water is 4186 J/kg·? C and the acceleration of gravity is 9.81 m/s2 . How high is the cliff if the temperature of 1 kg of water is raised 0.17?C? Answer in units of m.
