Arock of mass 0.24 kg falls from rest from a height of 20 m into a pail containing 0.40 kg of water. the rock and water have the same initial temperature. the specific heat capacity of the rock is 1850 j/(kg · c°). ignore the heat absorbed by the pail itself, and determine the rise in the temperature of the rock and water.
