1 kg aluminum dumbbell initially held 2 meters above the floor is allowed to fall. This experiment is performed inside a room whose dimensions are 10m × 5m × 3m. Assuming that the walls of the room do not conduct heat and that the room is empty (no other objects are presentesides the dumbbell itself), estimate the change of the temperature inside the room as a result as a result of dropping the dumbbell. Thermodynamic properties of Aluminum and air can be looked up.
i think i figured it out
