My problem is as follows "A 3 kg brick is dropped from a height of 1.0 m onto a nail which is vertically stuck in a plank of wood. If the nail doesn't move in much, how much heat is produced in the system when the brick hits and sticks onto the top of the nail." I know PE is 29.4J and this will convert to KE by the time it hits the nail but where does "heat" come into the picture?

  • Physics -

    The KE is converted to heat by friction on impact.

    Thanks so much.
