Question: A 2.2 kg brick is dropped from a height of 1.0 m onto a small nail stuck vertically in a piece of wood. Assuming the nail does not move in very much, how much heat is produced in the system when the block hits and sticks onto the top of the nail. (You can assume all of the energy becomes thermal energy gained by the nail.)
